Leonard James "Len" Mills (8 February 1898 – 16 May 1965) was an Australian rules footballer who played with West Torrens in the South Australian National Football League (SANFL) and St Kilda and Hawthorn in the Victorian Football League (VFL).

Mills, at 203 cm, is believed to have been at the time, the tallest ever VFL player.[3] He was a member of the 1924 West Torrens premiership team and counts games in that's years Hobart Carnival amongst his six interstate appearances.[4]
He played with New Town, a Tasmanian club, in 1926.[4] The next two seasons were spent back at West Torrens.[4]
Already 31 by the time he joined St Kilda in 1929, Mills kicked three goals on his VFL debut, against Fitzroy at Junction Oval.[5] The following season he kicked 17 goals from eight appearances for Hawthorn, which was enough to finish second in the club's goal-kicking behind Bert Hyde.[5]
