The Saskatoon Yellow Jackets were a baseball team that played in Saskatoon, Saskatchewan. The team was a member of the Western Major Baseball League, a collegiate summer baseball league operating in the prairie provinces of Canada. The team joined the league in 2002, but struggled financially throughout its existence and folded in 2014.

The Yellow Jackets began play out of Cairns Field in 2002. The team changed ownership multiple times and struggled with fan engagement.^[1][2] The team also struggled on the field, and missed the playoffs for six straight seasons from 2009 to 2014, finishing at the bottom of the Central division each of those years.^[3] The team folded in 2014.^[4] This left Saskatoon without a WMBL team until the city was awarded an expansion franchise, the Saskatoon Berries, in 2023.^[5]

In August 2017, two former Yellow Jackets dressed for the Seattle Mariners, marking the first time that two WMBL players dressed for the same Major League Baseball team. Andrew Albers, from North Battleford, pitched five innings on 15 August, while Marco Gonzales took the mound on 16 August.^[6]
