Leonard Sedgwick Howell (6 August 1848 – 7 September 1895) was an English footballer who won the FA Cup with the Wanderers in 1873 and made one appearance as a full back for England in the second international match.
After leaving the college, Howell joined the Wanderers and helped them retain the FA Cup which they had won 1872 final.
In the early stages of the final, Oxford "made the running... with Howell and Thompson performing admirably in the Wanderers defence to keep the University students at bay".
His solitary appearance for England had come three weeks before the Cup Final, in the second international match against Scotland played at Kennington Oval, London on 8 March 1873.
England selected a side with a strong Wanderers influence, including Charles Chenery, Robert Vidal, Alexander Bonsor, William Kenyon-Slaney and Hubert Heron.
