UFC 18: The Road to the Heavyweight Title was a mixed martial arts event held by the Ultimate Fighting Championship on January 8, 1999 in Kenner, Louisiana.

The event was seen live on pay per view in the United States, and later released on home video.

UFC 18 was technically part two of what the UFC called "The Road To The Heavyweight Title", a tournament, spanning four events, held to crown the new UFC Heavyweight Champion after the title was vacated by Randy Couture (due to contract disputes).

UFC 18 featured the first US appearance of MMA legend Bas Rutten, and the first appearance of the late Evan Tanner, who would go on to become the UFC Middleweight Champion.

The new logo used the similar character from the old logo (with hands on his hips instead of punching the globe) combined with the letters UFC on the bottom.
