The 2009–10 Perth Glory FC season was the club's 13th season since its establishment in 1996. The club competed in the A-League for the 5th time. Perth Glory changed their logo and for the first time in their A-League history chose to include vertical purple and white stripes on their home kit this season.
Season expectations were very high with Perth Glory's owner Tony Sage allowing manager David Mitchell to sign High calibre players like former Bolton defender Andy Todd and former Ajax midfielder Viktor Sikora who was on loan to Perth from FC Dallas the previous season. The club also managed to secure Socceroos Jacob Burns, Mile Sterjovski and Chris Coyne. Both Sage and Mitchell's intentions were to restore Perth's footballing past and challenge for an A-League finals spot. At one stage of the campaign the Glory were pushing to claim top spot and the league but a run of poor form and injuries cost the team and only managed to hold on to their final league position of 5th which equalled their best A-League finish in 2005–2006.
Perth Glory were knocked out of the A-League finals when they took part in a 1–1 draw against the Wellington Phoenix in Wellington which they lost to penalties and thus ended Perth's best season of the A-League so far.
