Harold Keenan (born 20 December 1893, date of death unknown) was an English professional footballer.
He spent his entire professional career with Blackpool in the early 1900s, making over 100 Football League appearances for the club.
Warrington-born Keenan made his debut for Blackpool on 25 January 1913, in a 4–2 defeat at Fulham.
He also made one league appearance the following season, 1913–14, in a goalless draw against Notts County at Bloomfield Road on 13 April 1914, fifteen months after his first start for the club.
He also helped steer the club to the third round of the FA Cup, at which point they were knocked out by arch-rivals Preston North End.
