Girl Names Starting With I

Ranks are overall positions among all 2025 girl names, so gaps between rows are real. For a random shortlist, spin I girl names in the generator, or scan the full top 100 girl names.

How common is I as a first letter for girls in 2025?

Among the 2025 top-1,000 girl names, 21 begin with I; summed, their births are 3.1% of the whole list, the 12th-largest share among the 26 initials. Tier by tier, the 2025 overall top 100 claims 4 of the table's 50 names (1 of those inside the top 10), the 101–500 band claims 4, the 501–1,000 band claims 13, and 29 rank past #1,000, outside the committed top-1,000 file. The table's last row, Iman, still carries 91 births at #2,072; any I girl names below it are outside the committed per-letter depth of 50 and are not shown.

Between #7 (Isabella, 10,666 births) and #2,072 (Iman, 91), the 50 rows of the 2025 I table hold 40,574 births in all, a top-to-bottom count ratio of 117.2. The middle row, the 25th, is Icelynn at #1,110 with 213 births in 2025. The widest jump between consecutive rows is 182 ranks, from Isabel (#177) to Itzel (#359); every 2025 girl name at the ranks between them begins with another letter. 4 rows carry exactly the count of the row above them, ordered by the SSA's alphabetical tie rule; the first such pair is Icelynn (#1,110) and Ines (#1,111), at 213 births each. The 4 names from the 2025 I table inside the overall top 100 are Isabella (#7), Isla (#28), Ivy (#39) and Iris (#61).

How a rank like #7 is assigned, including the SSA's alphabetical tie-break between equal counts, is explained in Reading ranks and counts.

I girl names across the decade snapshots

I girl names appear in the top 200 in 4 of the 7 snapshot years: 1955 (1 name, led by Irene at #147 with 2,433 births), 1995 (1 name, led by Isabella at #174 with 1,739 births), 2005 (3 names, led by Isabella at #6 with 15,197 births) and 2015 (5 names, led by Isabella at #5 with 15,667 births). In the other 3 (1965, 1975, 1985), no I girl name reached rank 200, which is where the committed decade files stop. The lead changed hands among 2 names across those 4 snapshots (Irene and Isabella), and Isabella leads again in 2025, at #7.

Measured as a share of top-200 girl births, I runs 0.2% in 1955, 0.0% in 1965, 0.0% in 1975, 0.0% in 1985, 0.2% in 1995, 2.4% in 2005 and 3.1% in 2015 — a high of 3.1% in 2015 and a low of 0.0% in 1965. Cut to the same top-200 depth, the 2025 list holds 6 I names with 4.1% of its births, led by Isabella at #7. To read those 7 I shares against the other 25 initials, for girls and for boys, see First-letter trends since 1955, where each snapshot column carries all 26 shares; the full index is on the data guides page.

Faded and new I girl names

Nothing has faded at the committed depths: each I girl name found in a snapshot top 200 is still on the 2025 list, and 6 of the table's 50 rows have at least one snapshot appearance.

The 2025 table also carries 44 names that no snapshot top 200 contains: Iris (#61), Itzel (#359), Ivory (#378), Iyla (#525), Izabella (#564), Ivanna (#567), Imani (#579), Indie (#634), Isabela (#664), Ila (#718), Iliana (#730) and Indy (#768), and 32 more. That records only that none of the 44, Iris at #61 included, ranked inside the top 200 in 1955, 1965, 1975, 1985, 1995, 2005, 2015; the snapshot files stop at that rank, so any of them can have been registered below it in any of those years.

The shape of the 2025 I list

Short names (four letters or fewer) number 21 in the 2025 I table, medium ones (five to seven) 25, and long ones (eight or more) 4. Take each length class on its own and the 2025 I list shows 4 long spellings from Isabella at #7 to Itzayana at #1,637, 25 medium spellings from Isabel at #177 to Ivanka at #2,028, and 21 short spellings from Isla at #28 to Iman at #2,072. By letter count, Ivy is the shortest spelling in the 2025 table (3 letters, #39) and Isabella the longest (8 letters, #7). "s" is the second letter of 11 of the 50 names in the 2025 I table, "n" of 10, and "v" of 8; 12 second letters are used in total.

Across the sexes, 5 of these 50 spellings also sit on the 2025 boys' I list, where the SSA ranks each sex on its own: Indy (#768 for girls, #2,369 for boys), Indigo (#854 for girls, #1,531 for boys), Ira (#1,086 for girls, #822 for boys), Isa (#1,717 for girls, #933 for boys) and Iman (#2,072 for girls, #1,798 for boys).

I girl names: questions the data answers

What is the most popular girl name starting with I in 2025?

Isabella. The 2025 SSA data records 10,666 girls named Isabella, which places it at #7 among all girl names that year, inside the overall top 10.

How many girl names starting with I are in the 2025 top 1,000?

21. Together they account for 3.1% of the births in the 2025 top 1,000, the 12th-largest share among the 26 initials.

Why does this page list 50 I girl names?

The committed per-letter file holds the 50 most-registered 2025 girl names for each initial, and I fills it: the 50th row is Iman at #2,072. Any I names below that cut are outside the committed depth and are not shown.

Which I girl name on this page has the lowest rank?

Iman, at #2,072 with 91 births in 2025. Ranks are overall positions among all 2025 girl names, so the span from #7 to #2,072 covers names that start with other letters.

How many I girl names were in the top 200 in 1955 and in 2015?

1 in 1955 (led by Irene at #147) and 5 in 2015 (led by Isabella at #5). Those are counts inside one SSA year's top 200; over the 7 snapshots the I count ranges from 0 (1965) to 5 (2015).

Do any of these I girl names also appear on the boys' I list for 2025?

Yes, 5 of the 50: Indy (#768 for girls, #2,369 for boys), Indigo (#854 for girls, #1,531 for boys), Ira (#1,086 for girls, #822 for boys), Isa (#1,717 for girls, #933 for boys) and Iman (#2,072 for girls, #1,798 for boys). Those are per-sex ranks, so Indy's #768 for girls (353 births) and #2,369 for boys (58) are two separate SSA positions, not one.
