Connors State School of Agriculture came into existence in 1908. The State Board of Agriculture was the school’s governing board and the school was named after the Board’s first chairman, John P. Connors. Classes were first held in downtown Warner in 1909. In 1911, the present Classroom Building was constructed and the
school moved to its present location, one mile west of Warner. Connors State Agricultural College became a fully accredited junior college in 1927. The State Board of Agriculture governed Connors until 1944. That year the Legislature created the Board of Regents for the Oklahoma Agricultural and Mechanical Colleges. This Board then became the governing board of Connors State Agricultural College. In 1967, the Oklahoma Legislature changed Connors’ name to Connors State College of Agriculture and Applied Science. The College’s name was changed again by the Oklahoma Legislature in 2002 to Connors State College.

In 1977, Connors began regularly offering off-campus, extension courses in Muskogee at various public school locations. In 1985 classes were moved downtown to the Holly Building at 4th and Broadway. In 1986 Connors purchased the Holly Building, renovating it in 1989. In 1988, Muskogee became a branch campus offering resident college credit courses and programs.
Connors received title to the C.N. Haskell Building located at 2nd and Court Streets in downtown Muskogee in 1992. In 1993, the downtown Muskogee campus was moved from the Holly Building to the Haskell Building.

In, 1994, Connors acquired 42 acres of land in the northeastern section of Muskogee for the construction of a classroom/science facility. The Three Rivers Port Campus opened for classes in 1996.

In 1993, Connors also received title to a 1,316 acre ranch site located five miles south of the Warner campus. The South Ranch contains farmland, wetlands, and wildlife habitat.
