Joseph John Keenan (born 14 October 1982) is an English left-sided midfielder who made three appearances for Chelsea in 2002, having joined the club as a youngster.
A product of Chelsea's youth system, Keenan made his debut on 9 February 2002, replacing John Terry in a 1-1 away draw against Aston Villa, having previously featured on the Blues' bench on eleven occasions without appearing. Claudio Ranieri then withdrew Keenan from the England Under-20 squad in order that he be available for the next match; an FA Cup tie against Preston North End, and stated that he considered the youngster to be a fine prospect for Chelsea: "Joe played well last week, with personality. I believe in this young boy. He is intelligent. He has a good left foot. I think he can do well next season."  Keenan made another late substitute appearance in the match, this time replacing Gianfranco Zola in the 3-1 win.
He made a second brief league appearance early in the following season, as a late substitute in a match against Newcastle, but broke his leg a short while later in a reserve match against Arsenal.  The injury kept him out for most of 2002-03, and when Ranieri was replaced by José Mourinho at the end of the season, with money available to strengthen the squad following the takeover by Roman Abramovich a year earlier, it was apparent that he would have to go out on loan to gain further experience of first team football.
Keenan joined Belgian side VC Westerlo on loan in the latter half of 2003-04, where he featured regularly over the next 18 months, before a brief loan spell at Chelsea's west London neighbours Brentford in 2005, and a move to Dutch side Willem II.
Keenan then moved to Australia, playing for Melbourne Victory as a left wing-back during the 2007-08 season. He returned to the UK to play for Scottish Premier League side Hibernian in July 2008. He scored his first goal for the club in a Scottish League Cup defeat against Morton, but struggled to hold down a first team place and was eventually released. Keenan returned to Australia in December 2009 to play for South Melbourne,  and later joined Adelaide United on loan in August 2010 as injury cover. He was one of Adelaide's most consistent players over the following months, and had his contract extended in December, but the Englishman suffered a setback when he broke his leg for the second time in his career in a match against Brisbane Roar at the beginning of 2011.
