During the 2004–05 English football season, Crystal Palace competed in the FA Premier League, following promotion from the First Division (renamed the Championship) the previous season.
Despite the 21 league goals of striker Andy Johnson, and being just ahead of the relegation zone for most of the season, Palace were unable to remain in the top flight and were relegated on the last day of the season, following a 2–2 draw with fellow south-east London rivals Charlton Athletic at The Valley, combined with West Bromwich Albion's 2–0 win over Portsmouth. With relegation, speculation reigned over Johnson's future; Johnson even handed in a transfer request, but ultimately the striker would sign a five-year contract with the club with an improved wage, pledging to help the club regain top-flight status.
Young winger Wayne Routledge also impressed with 10 assists in the Premier League, making him more productive than the likes of Arjen Robben and Steven Gerrard in terms of creativity, but he was snapped up by Tottenham Hotspur following Palace's relegation.

Italian company Diadora became Palace's new kit manufacturers, and introduced a new home kit for the season. The home kit featured red shorts and socks (dispensing with the navy attire of the previous two seasons) and predominantly red shirts with blue stripes. The away kit featured white shirts with blue arms.
Churchill Insurance remained kit sponsors for the fifth consecutive season.
