Stephanie Catley (born 26 January 1994) is an Australian football player currently playing for Portland Thorns FC of the NWSL.
A talented youngster who played for the South East Cougars in Football Federation Victoria's Victorian Champions League program, Catley made her senior debut at a young age; playing Perth Glory at only fifteen years of age in October 2009.
Playing predominantly in the midfield, Catley was a key figure in a young team and scored her maiden goal in her second season as she scored an equaliser three days before her birthday against Perth Glory in January 2011.
Following a switch to defence for the 2011/12 season, Catley had her most impressive season to date and was rewarded by winning Female Footballer of the Year.
At the end of the 2013–14 W-League season, Catley signed with NWSL team Portland Thorns.
Having spent years playing in the youth teams of Australia, Catley made her international senior debut against New Zealand in June 2012, the same match as her childhood friend Ashley Brown.
