Real World/Road Rules Challenge: Battle of the Sexes 2 is the 9th season of the MTV reality game show The Challenge (at the time known as Real World/Road Rules Challenge).

Battle of the Sexes 2 is the first season of The Challenge to be a sequel from an earlier season, the show's sixth season, Battle of the Sexes.

Battle of the Sexes 2 premiered on October 4, 2004, and concluded on January 31, 2005.

The season took place in Santa Fe, New Mexico. Before each challenge, each team would choose three leaders. If the team won, those three leaders would form the inner circle and decide whom to vote from their team; if the team lost, the rest of the team would form the inner circle and vote off one of their three leaders. No life-shields were used during this season.

This season was preceded by The Inferno and followed by The Inferno II.
