Meaning and history
Douglas comes from a Scottish surname derived from the name of a town in Lanarkshire, which was itself named for the Douglas Water, a tributary of the River Clyde. The name means “dark river,” from Gaelic dubh “dark” and glais “water, river,” an archaic word related to glas “grey, green.” It was the name of a Scottish Lowland clan whose leaders were powerful medieval earls, and its Gaelic forms are Dùghlas and Dùbhghlas. It has been used as a given name since the 16th century.
Douglas rose from #848 to #807 for boys between 2024 and 2025. Its highest annual birth count came in 1957, with 16,730 births.
