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. 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.
