Truax is an unincorporated community in the Rural Municipality of Elmsthorpe No. 100, Saskatchewan, Canada. It held village status prior to December 30, 1970. Truax is located 80 km (50 mi) southwest of Regina and approximately 75 km (47 mi) southeast of Moose Jaw.
Truax is situated almost equidistant between Radville and Moose Jaw on the Canadian National Railway line that was closed by CN in the late 1980s. Southern Rails Cooperative, a farmer-owned cooperative, took over operation of the line, and it still operates today, with farmers loading their grain directly into rail cars, bypassing the grain companies, and shipping directly to port. The rail line terminates at the Truax grain elevator, built in 1964 and now given Saskatchewan Heritage status.
At its peak, Truax had a lumberyard, a gas station, a hardware store, a school, an indoor rink and a curling rink, and two churches (Anglican and Roman Catholic). The gas station and convenience store closed in the mid 1980s. St. Anne's Roman Catholic Church is no longer open, but when it was mass was held every Saturday night at 7:00 in the winter, and 7:30 in the summer. St. Anne's Roman Catholic Church was decommissioned as an official Roman Catholic Church on Sunday, June 25, 2012.
