The 1998 NCAA Division I Cross Country Championships were the 60th annual NCAA Men's Division I Cross Country Championship and the 18th annual NCAA Women's Division I Cross Country Championship to determine the team and individual national champions of NCAA Division I men's and women's collegiate cross country running in the United States.

In all, four different titles were contested: men's and women's individual and team championships.

The men's team championship was won by Arkansas (97 points), the Razorbacks' ninth overall.

The women's team championship was won by Villanova (106 points), the Wildcats' seventh (and first since winning six consecutive between 1989 and 1994).

The two individual champions were, for the men, Adam Goucher (Colorado, 29:26) and, for the women, Katie McGregor (Michigan, 16:47).
