Alga is an uncommon, botanical-based given name of Slavic origin, particularly from Russia and other Eastern European countries. It means "seaweed" or "algae." This name may appeal to those who appreciate nature-inspired monikers or have a connection to marine life.
The name Alga appears to have been moderately popular during the late 19th and early 20th centuries, with a noticeable peak in usage between 1914 and 1928. After 1931, there's a significant gap until one birth is recorded in 1955. Overall, Alga was not among the most frequently chosen names during this period, with only 132 births recorded over approximately 67 years.
