Sir Charles Cuyler, 4th Baronet, (15 August 1867 – 1 October 1919) was an English first-class cricketer and British Army officer.
The son of Sir Charles Cuyler, he was born in August 1867 at Almondsbury, Gloucestershire and was educated at Clifton College. His father died during his final year at Clifton, with Cuyler succeeding him as the 4th Baronet of the Cuyler baronets in August 1885.

He was promoted to lieutenant in January 1890, with promotion to captain coming in January 1895.

Batting twice in the match, he was dismissed in both MCC innings' without scoring by Ernest Ensor and Robert Gwynn respectively. He became an instructor at Sandhurst in August 1897, a post he held until January 1903. He was seconded for service as an adjutant of volunteers in January 1904. He retired from active service in September 1907, by which time he held the rank of major.
