Isla is a feminine given name traditionally of primarily Scottish usage, derived from Islay, the name of an island off the west coast of Scotland. It is also the name of two Scottish rivers. The root word itself has no known origin. The name has seen a dramatic surge in popularity in English-speaking countries in the 2010s and 2020s, becoming a common choice for girls in the United Kingdom, Australia, New Zealand, and the United States.Etymology and HistoryThe name originates as a variant of the Scottish Gaelic island name Islay (Gaelic: Ìle), whose etymology is debated but may be pre-Gaelic. I the meaning of Isla is usually given simply as “island,” a sense reinforced by its coincidental spelling match to the Spanish word isla meaning “island,” though the pronunciations differ (Eye-la vs. ees-la). The name originally appeared in masculine forms like Ilay or Islay, borne by figures such as Ilay Campbell (18th-century Scottish politician), and remained rare as a female name until the late 20th century. Today, Isla is regarded as distinctly feminine, while Islay persists as a rare male name.Cultural SignificanceThe shift in gender association may be linked to notable bearers in popular culture, including a well-known fictional character (Isla Fisher in Wolf Like Me), which likely boosted adoption. The name’s soft sound and two-syllable rhythm align with modern baby–naming trends favouring vowel–starting short names common for girls in English–speaking lands.Notable BearersNotable people named Isla include:Isla Blair (born 1944), British actress known for The Bell and Henry VIsla Blomfield (1865–1959), Australian nurse and sanitary inspector during World War IIsla Cameron (c. 1930–1980), British folk singerVariants and SpellingsVariant forms include Islay (the original Scottish spelling), as well as Iyla and Ila originating from alternate historical spellings.
