Meaning and history
Isla is a variant of Islay, typically used as a feminine name. Originating in Scotland, it became very popular in the English-speaking world during the 2010s and 2020s. The spelling also matches the Spanish word isla, meaning “island,” though it is pronounced differently.
Isla has made a dramatic comeback. After first appearing in the US records in 1886, it fell to #955 by 1908, before climbing to #28 in 2025. That year also produced its highest recorded birth count, at 6,012.
