Thomas Harley (born 18 July 1978) is a former professional Australian rules footballer who played for the Port Adelaide Football Club and the Geelong Football Club in the Australian Football League (AFL). A defender at and , Harley is a two-time premiership-winning captain at Geelong.
After a successful junior career which culminated with selection in the under-18 All-Australian team, Harley was drafted to Port Adelaide as a zone selection. Although an inaugural member of the club, Harley struggled to force his way into the senior team and spent the majority of his early years playing for Norwood in the South Australian National Football League (SANFL). After making just one appearance for Port Adelaide, Harley was traded to the Geelong Football Club in exchange for the 37th draft pick in the 1998 AFL Draft.

Harley quickly established himself within the Geelong defence and received a range of accolades and club honours, including multiple Best Clubman awards. Prior to the 2007 AFL season, Harley was appointed club captain and went on to enjoy great individual and team success. He led the club to its first premiership in 44 years during 2007, and became a dual premiership captain after their victory in 2009. In between, he achieved All-Australian honours as vice-captain of the team, and won the AFL Players Association (AFLPA) Best Captain Award. Harley also participated in the 2008 AFL Hall of Fame all-star game, and was inducted into the Geelong Football Club Hall of Fame.

He is noted for being a leading ambassador to various community campaigns, including the anti-violence program 'Just Think' and Barwon Health. Since his retirement as a player, Harley has undertaken various roles in the sporting industry: he held the position of "General Manager - Football" with the Sydney Swans, and became their CEO in 2019.

Early life
One of three children born to Rick and Trish (née Rofe) Harley in Adelaide, South Australia. Tom played most of his junior football for the Walkerville Junior Football Club and St Peter's College from the under–11s to under–15s.
Despite being regularly overlooked for a place in the elite South Australian junior state squads, he continued to follow the rest of the squad to training sessions in order to learn alongside them. Harley's persistent attendance at training was rewarded when he was called up to the under–18s squad as a late injury replacement a week prior to the National AFL Championships. Playing at centre half-back, Harley's performance in defence earned him end-of-year All-Australian honours and brought him to the attention of AFL scouts.
AFL career
Port Adelaide experience (1998) Following their entry into the AFL in 1997, Port Adelaide drafted Harley to the club as part of their zone selections, which entitled them to recruit uncontracted players from the South Australian National Football League (SANFL) prior to the 1996 National Draft. He struggled to break into the Port Adelaide senior team, and often found himself playing in the SANFL reserves for Norwood during the 1997 season, where he helped the team reach the SANFL reserves Grand Final, where they were defeated by Port Adelaide. Harley's contributions in the reserves team throughout the year saw him promoted to the senior Norwood side, where he featured in two of their SANFL finals before missing selection for the senior SANFL Grand Final.
Harley continued to ply his trade in the SANFL reserves during the 1998 season, before being rewarded mid-season with a senior team debut for Port Adelaide in round fourteen against Geelong. The team opted to use Harley sparingly off the bench, with Harley's only meaningful contribution being a late goal scored with his only kick for the game. Returning to the Norwood reserves team, Harley helped the team reach their second successive Grand Final appearance against Port Adelaide and capture the reserves premiership. However, after struggling to break into the senior side, Harley was traded to Geelong during the off-season for the 37th pick in the 1998 AFL Draft.
Mixed success (1999–2006) Harley made his debut for Geelong in round fourteen of the 1999 AFL season against Adelaide, and kept his position in the senior team for the final nine games of the home-and-away campaign. The following season, Harley helped Geelong achieve a 12-9-1 record to qualify for the finals series. Harley made his finals debut in the First Elimination Final against Hawthorn, where he gathered 7 disposals and took 2 marks in the clubs' nine-point loss.
