Meaning & origin

Alga is a rare feminine name that first appeared in U.S. records in 1888. It saw its peak usage in 1903, but never entered the top 1000 names in any year, reflecting its status as a true rarity. The name's trajectory has remained stable, with only occasional births in recent decades. Its meaning is uncertain, possibly derived from Lithuanian names or the scientific term for seaweed. Alga has never been strongly associated with any particular state, and its similar names like Elva and Alva suggest a vintage, concise style.

Alga likely emerged as a diminutive or variant of longer names like Algirdas (Lithuanian) or Alge (Scandinavian). It may also have been inspired by the Latin word 'alga' meaning seaweed, used in scientific contexts. The name saw sparse use in the United States in the late 19th and early 20th centuries, particularly around 1903, but never gained significant popularity.
