Louis Cottrell (December 25, 1878 – October 17, 1927) was an influential American jazz drummer. "Old Man" Cottrell was the father of Louis Cottrell Jr. and great-grandfather of New Orleans jazz drummer Louis Cottrell.

Cottrell was born and died in New Orleans. He played with John Robichaux's orchestra in 1909 and with the Olympia Orchestra in New Orleans from 1900 to 1915. From 1916 to 1918 he played in Chicago with Manuel Perez, then played with A.J. Piron until the time of his death.
