Isla (/ˈaɪlə/ EYE-lə) is a feminine given name traditionally of primarily Scottish usage, derived from "Islay", which is the name of an island off the west coast of Scotland.

The name has increased in popularity in recent years in English-speaking countries.

[1][2][3] The name in its original form was Ilay or Islay (e.g. Ilay Campbell), and it was a masculine given name, and was rare among women.

Today Isla is regarded as a distinctly female name and Islay a rare male name.

Other forms of the girls' name derived from alternate historical spellings of the Scottish island's name include Ile, Ila, and Eylah.
