Meaning & origin

Irja is a rare Finnish name that saw modest use in the United States during the 1910s, particularly in 1915 when it reached its peak popularity. The name first appeared in U.S. records in 1910, and by 2025, it was recorded fewer than five times in total over the entire century. With no recent births reported, Irja remains an obscure choice, primarily found among Finnish-American families. Its trajectory has been stable, meaning it has never experienced a significant revival. While its exact etymology is debated, many connect it to the Finnish word for 'peace' or consider it a northern European variant of the classical name Iris.

Irja is a Finnish feminine name of uncertain derivation. It may be a variant of Iria, which itself is possibly related to Iiris, the Finnish form of Iris, or derived from the Baltic word for 'peace'. The name saw modest use in the early 20th century in Finland and among Finnish immigrant communities.
