The 2018 Colorado Rapids season will be the Colorado Rapids' 23rd season of existence, their 23rd season in Major League Soccer and their 23rd season in the top-tier of American soccer. Due to a reconfiguration in the CONCACAF Champions League format, the Rapids will begin play in the Champions League this year for their successes during the 2016 season. Colorado opens their slate of competitive fixtures on February 20 in the Champions League Round of 16 with a two-legged series against Canadian champions, Toronto FC in the round of 16. On March 3, the club will have their MLS opener against Chicago Fire. In either May or June, the Rapids will begin play in the U.S. Open Cup.
