The 2005 Chinese Super League season was only the second season of China's top-tier football competition. With no relegation the previous season, the league expanded from 12 to 14 clubs with the promotion of Shanghai Zobon and Wuhan Huanghelou. The season was scheduled to start on 5 March 2005, but was postponed until April due to a sponsorship problem and finished on 5 November with Dalian Shide, seven-time champions in the old first division, clinching their eighth title. Defending champions Shenzhen Jianlibao finished third from bottom, the second consecutive year in which the defending champions has done so.
