Names of Iceland IS

In Iceland the second name is a patronymic — the father's given name, renewed each generation — rather than an inherited family name; Hagstofa Íslands — most common ættarnöfn (Hagtíðindi 2018) records Blöndal as the commonest surname in Iceland.

No inherited surnames here

Icelandic naming is patronymic (Jónsson/Jónsdóttir) and inherited family names (ættarnöfn) have been legally closed to new adoption since 1925, so the stock is a small fixed list — 639 harvested from is-hagstofa-aettarnofn and is-arnastofnun-aettarnofn, which is close to complete. The high-value Icelandic target is GIVEN names plus the Mannanafnaskrá approved-names register, not surnames. Our record corpus does hold "surnames" for this country, but they are largely records of residents from elsewhere, so we do not publish them as a ranking.

Where the two lists disagree

24 of Hagstofa — population register names 2023's top 25 given names sit five or more places away in our record corpus. Neither ranking is wrong; they count different people.

Hagstofa — population register names 2023, 2023 on the left; every record we hold for Iceland on the right. A dashed line means the name is not in our top ranks for this country at all.

The register counts one population in one year — everyone it enumerates, once. Our corpus counts records: historical registers going back decades, the diaspora, business and place records, and several generations of births. A name that was common two generations ago outranks a name common today; a name whose spelling scatters across sources (diacritics dropped, transliterated differently) loses ground, because only its dominant spelling is ranked.

Characteristic of Iceland

Not the most common names — the most distinctive ones. A name appears here when Iceland holds a larger share of its bearers than the world does, weighted by how much of the country's whole name distribution it accounts for.

Scripts & spelling

The best-attested names in Iceland, in the spelling our records use there. Where a Latin spelling is also attested it is shown beneath — a spelling from the corpus, not a machine romanisation.

The Latin alphabet here is not the ASCII one. Stripping diacritics merges names that are not the same name and changes how they are pronounced, and a record that has been ASCII-folded has lost information no amount of guessing recovers.

Countries whose names look alike

Measured as the overlap between each country's top 300 given-name forms, weighted by how common each is — the fuzzy-set approach of Lauc (2024), on a truncated inventory.

    What we know about this register

    The only official ættarnafn FREQUENCIES: 'Algengustu ættarnöfnin voru Blöndal (324), Thorarensen (293) og Hansen (282)' at 2017-01-01, against 640 registered ættarnöfn of which nearly 400 were actually borne, by about 12,000 people (~4% of the population). Same Hagtíðindi release ('Mannanöfn og nafngiftir á Íslandi', 2018-02-26) already held as is-hagstofa-naming-practice, whose parser took only the given-name top-3 and MISSED the surname section entirely — hence this separate surname-only source. Only 3 rows, but they are the sole bearer counts in existence for Icelandic family names; the existence list is is-arnastofnun-aettarnofn. The three figures are asserted in the fetcher and VERIFIED against the live PDF text at runtime, so an upstream revision fails loudly instead of silently. Neither Þjóðskrá nor the StatBank publishes any surname table: svc.skra.is NafnTidni rejects kenninafn=/eftirnafn=/millinafn= with HTTP 400, and px.hagstofa.is has given-name tables only.

    What we know about this register

    Per-name query API from the National Registry (Þjóðskrá). FULLY ENUMERATED as of 2026-07-30: the name parameter is a SQL LIKE pattern, so eiginnafn=A%25 returns every registered name starting with A, and one query per initial letter dumps the whole register — 34,166 eiginnafn + 22,634 annadnafn = 46,901 distinct names ever borne. This REPLACED a seed-list probe that reached only 9,005 names (19% coverage); every probed name was a subset of the enumeration, so nothing was lost. Enumerate a-z plus the Icelandic letters á é í ó ú ý þ æ ö ð and the Nordic å ø: diacritic folding applies only to letters OUTSIDE the Icelandic alphabet (ā%25 == a%25, ś%25/ş%25 == s%25), while Icelandic letters collate as distinct. `%25` alone times out (504); there is no row cap (summing two-char prefixes a?%25 reproduces the a%25 total exactly) and NO suppression threshold — exact counts are returned down to 1. svfn is optional; 9999 = 'Allt landið'. Each response is a yearly series (FjoldiAr) of living bearers in that position; the CURRENT-year figure is a rolling live value, not a 1 January snapshot (observed to move within days). ONE ROW PER NAME with count = first + second position, the split kept in data_note as position_first=/position_second= — emitting the two positions as separate rows was unsafe because build_combined dedupes on (source_id, name, sex, year, name_type, region_code) and silently dropped one of them. data_note also carries status=current or status=historical;last_seen=YYYY (12,753 names whose series died out; these include 614 patronymic-shaped registry artifacts such as Ívarsdóttir/Bjarnason that sat in the eiginnafn field and went to 0 in 2023 — filter on status, NOT on a -son/-dóttir suffix, since Jason/Nelson/Mason/Madison are genuine current given names). name_type is 'given' for BOTH slots: `annadnafn` is a POSITION, not the legal category millinafn — 3,626 committee-approved eiginnöfn occur in that slot against only 218 approved millinöfn, and it also holds family-derived middle names in no register at all (annadnafn=Blöndal -> 55-65 bearers, absent from Mannanafnaskrá). The authoritative millinafn flag is is-mannanafnaskra type=millinafn. NO SURNAME ROWS: the API exposes no kenninafn/eftirnafn dimension (those params return HTTP 400) and annadnafn=Jónsson / Jónsdóttir return []; note however that eiginnafn=Jónsson DOES return data (8 bearers in 2021, 0 from 2023). Icelandic hereditary surnames come from is-arnastofnun-aettarnofn. Fetcher scripts/fetch_is_skra.py; raw JSON cached under raw/IS/skra_enum/.

Sub-national registers

1 register for Iceland publishes regional lists only (Hagstofa Íslands — Icelandic names and naming practice (2018)). A regional list is not a national one, and summing regions would be an aggregate the publisher never made, so no figure on this page comes from them.

About this data

Official figures are reproduced from the register named beside them, at the year named beside them, and are never combined across registers. The "across all records" ranking counts records in our own corpus — historical registers, the diaspora, business and place records — and is not a population count. Bearer estimates are omitted where a name accounts for more than a quarter of a country's records, because the estimate is not defensible there. Names listed by reference works and licensed name dictionaries are cited as attesting a name; their figures are not published.

Questions

What is the most common given name in Iceland?
Anna, according to Hagstofa — population register names 2023 (2023), with 4,782 bearers recorded among girls.
What is the most common surname in Iceland?
Blöndal, according to Hagstofa Íslands — most common ættarnöfn (Hagtíðindi 2018) (2017), with 324 bearers recorded.
Why do sources disagree about the commonest name in Iceland?
Because they count different people. Hagstofa — population register names 2023 (2023) counts one population once, and its commonest given name is Anna. Our corpus counts every record we hold — historical registers, the diaspora, decades of births — and its commonest is Guðrún. Both are on this page, each with its denominator.
Do people in Iceland have surnames?
Icelandic naming is patronymic (Jónsson/Jónsdóttir) and inherited family names (ættarnöfn) have been legally closed to new adoption since 1925, so the stock is a small fixed list — 639 harvested from is-hagstofa-aettarnofn and is-arnastofnun-aettarnofn, which is close to complete. The high-value Icelandic target is GIVEN names plus the Mannanafnaskrá approved-names register, not surnames.
