August Bohlin (born 7 July 1877 Österlövsta; died 19 May 1949) was a nyckelharpist and fiddler from Uppland, Sweden.

He is known for developing the three-row nyckelharpa of today in 1929.

August came from a musical family; his father Johan was a skilled nyckelharpist.

Father and son produced three albums together in 1913 (Odeon 840, 845 and 847).
