The 2018 Columbia Lions football team represented Columbia University in the 2018 NCAA Division I FCS football season as a member of the Ivy League.

They were led by fourth-year head coach Al Bagnoli and played their home games at Robert K. Kraft Field at Lawrence A. Wien Stadium.

The Lions hosted Ivy League foes Princeton, Dartmouth, Yale, and Cornell, and traveled to Penn, Harvard, and Brown.

Homecoming coincided with the game against Dartmouth on October 20.

In 2018, Columbia's non-conference opponents were Central Connecticut of the Northeast Conference, Georgetown of the Patriot League, and Marist of the Pioneer Football League.
