Risto Mannisenmäki (born on 28 May 1959) is a former rally co-driver and two-times world champion with driver Tommi Mäkinen.

[1] Mannisenmäki begun his career in 1982 and was co-driving for various drivers such as Tommi Mäkinen, Sebastian Lindholm and Ari Mökkönen in local rallies.

For the 1998 season, Mannisenmäki moved on to co-drive with Tommi Mäkinen, after the retirement of Seppo Harjanne.

During the Rally of Corsica in the 2001 WRC season, both were involved in a major accident where the Lancer driven by Mäkinen and Mannisenmäki ricocheted off of the outside wall into steep cliff-face, turning the car over and narrowly avoiding plunging down the ravine on the opposite side of the road.

In the accident, the passenger-side of the Lancer was heavily damaged, breaking Mannisenmäki's back, forcing an end to his co-driving career.
