The club has had four main crests since its inception in 1904. The origin of the current crest goes back to 1908, when Sport Lisboa merged with Grupo Sport Benfica. Back then, only red and white colours were displayed on the crest. In 1930, the crest was altered and the colours from the flag of Portugal were added. Sixty-nine years later, in 1999, the crest was changed again. The most significant changes were the modification and repositioning of the eagle and the reduction of the wheel's size.
