Frank John Minnitt (3 September 1894 – 12 May 1958) was a British illustrator and cartoonist who drew for over 100 comic papers from the 1920s to the 1950s. He is perhaps best known for his depictions of Billy Bunter in the comic Knockout between 1939 and 1958. He married Alice Davie in 1919, and had a daughter Betty (1920–2009). He married Evelynne Thelma Snell (1912–2003) in 1947 and with her had a son, John Frank Minnitt (born 1950). On his death the drawing of Billy Bunter in Knockout was taken over by artists Eric Roberts and Reg Parlett.
