Kimo Leopoldo (born January 5, 1968 in Munich, Germany) is a mixed martial artist, often billed as simply Kimo . He made his MMA debut at UFC 3 in 1994. Kimo's fighting style has been described as freestyle, with a mixture of striking and grappling techniques.

He was erroneously credited with a black belt in Taekwondo in his Ultimate Fighting Championship debut at UFC 3 (he later admitted to lying in order to be granted the opportunity to fight).

Kimo is well known for his Christian beliefs: he sports many religious tattoos, and entered the arena at UFC 3 carrying a large cross on his back.

In UFC 3, he lost to UFC 1 and UFC 2 champion Royce Gracie but succeeded in wearing down the smaller fighter, causing Gracie to forfeit his next match. Kimo returned at UFC 8 and fought Ken Shamrock, losing early in the fight.

Kimo would then go on to victories over Paul Varelans, professional wrestler Bam Bam Bigelow and Brian Johnston. Returning to the UFC at UFC: Battle in the Bayou, Kimo would lose a decision to Tsuyoshi Kohsaka, and did not fight again for four years.

After a warm up fight against Tim Lajcik in the WFA in 2002, Kimo again returned to the UFC at UFC 43, where he quickly defeated David Abbott "Tank" by arm triangle choke. Kimo went on to fight in the main event of UFC 48, where he fought Ken Shamrock in a rematch. Kimo was knocked out in the first round from knees to the head.

In his two most recent fights, Kimo lost to Dave Legeno by submission. He then lost to Wes Sims by TKO in X-1.
