The Chelsea logo features the lion rampant regardant in a blue circle, which is outlined with gold on the inside and outside. The circle bears the club’s name, two balls and two roses, which are England’s national symbols.

The lion in the crest was taken from the Arms of Earl Cadogan. And the staff is that of the Abbot of Westminster whose jurisdiction extended over Chelsea. The Three roses were used to represent the country of England and the two footballs were added to represent the game.

For one season, they switched to a blue shield with the letters 'CFC' branded on them before they turned to a design which resembles their current logo, with a lion holding a staff in the middle of a blue circle. 'Chelsea Football Club' and red roses featured on the outer edge of the circle, while the outline was a bright yellow.
