Swift Current Presbytery was one of the original 16 presbyteries established by the first General Council of the United Church of Canada (June 1925), to be part of the new Saskatchewan Conference.

Prior to Union, in 1925, there had also been a Swift Current District, in the Saskatchewan Conference of the Methodist Church.

In 1959, the presbytery was amalgamated with part of Assiniboia Presbytery (west of Highway 19) and became Cypress Hills Presbytery.
