Sydney Roosters Logo

Eastern Suburbs did not traditionally sport a crest on their jerseys in the first half of the 20th century.Other clubs occasionally sported simple designs on their strip; however, this was not seen consistently on all jerseys until the 1950s and 1960s. In 1967, the club introduced the first logo, displaying the motto "Easts to Win", following a winless season. The crest also incorporated a rooster or cockerel in the design; one source suggested that this choice of mascot followed after the Roosters' jersey design was inspired by the French national team's jersey. Given that the French team's mascot was affectionately known to supporters as le coq, "the rooster", connections have been made as to the choosing of a rooster for Eastern Suburbs' mascot.

In 1978, the motto was replaced with the team's name, "Eastern Suburbs". This name was kept until 1994, when the club changed its playing name to the "Sydney City Roosters" for the start of the 1995 season to expand the club's widening fan base. In 2000, the club changed its name to the "Sydney Roosters".

Although marketing names have changed, the Roosters are still registered with the National Rugby League competition as the Eastern Suburbs District Rugby League Football Club.
