The Cyclocross Crusade, currently in season 31, is a cyclo-cross race series based in Portland, Oregon held over an eight-week period during the months of October and November. As of 2005, the series was the largest cyclo-cross series in the United States.^[1][2] The 2006 series consisted of six races plus the U.S. Gran Prix of Cyclocross final (a Union Cycliste Internationale (UCI) sanctioned event). The Cross Crusade began hosting UCI-sanctioned events as part of the series in 2002.

The first Cross Crusade was held in 1993, and was an expansion of a three-race series called First Mud, which had only included elite participants,^[3] and which had been held since the mid-1980s.^[4]

There were no races in 2020 caused by the COVID-19 pandemic. That was deferred to 2021.
