The Inferno II is the 10th season of the MTV reality game show, The Challenge. The season is directly subsequent to Battle of the Sexes 2.

The Inferno II is the second of The Inferno series, with the original Inferno airing in 2004, and The Inferno 3 following in 2007. The show aired in 2005, and took place in Manzanillo, Mexico. This challenge was the same as The Inferno, except this time each team was allowed to choose only one "Inferno nominee" from the opposite team. This nominee had to win the "life shield" to save him or herself. The contestants in this challenge were grouped into two teams of "Good Guys" and "Bad Asses", representing the "heroes" and "villains" of their respective seasons.
