2017–18 Chicago State Cougars men's basketball team

The 2017–18 Chicago State Cougars men's basketball team represented Chicago State University during the 2017–18 NCAA Division I men's basketball season. The Cougars, led by eighth-year head coach Tracy Dildy, played their home games at the Emil and Patricia Jones Convocation Center as members of the Western Athletic Conference. They finished the season 3–29, 1–13 in WAC play to finish in last place. They lost in the quarterfinals of the WAC tournament to New Mexico State.

The Cougars had the worst average point margin in Division I at –22.7 points, despite winning two games by over 40 points.

After the season, Chicago State fired Dildy during the week of March 5, 2018, although it was not officially announced until a week later. After a nearly a five-month search, Lance Irvin, a Chicago native and former assistant coach at DePaul and several other schools, was named the new head coach of the Cougars on August 7.
