Celtic's first crest, was the Celtic Cross, as was seen on the first strip. However advertisements of Celtic in the early years, showed a harp against a blue background. The team also wore a strip with a large shamrock as the badge in the fifties, then the strips were without a crest until the late seventies, when the four leaf clover became the emblem, which is still used to present day. The Celtic Cross did make an appearance again in the "Centenary Year" and in 2003, to celebrate 100 years of the hoops.

The current badge is an amendment of the previous badge after the takeover in 1995 where the club changed to being a Public Limited Company from being a private limited company, hence the old name around the badge had to change. The only significant change was that the name around the badge now stated "The Celtic Football Club" as against "The Celtic Football and Athletic Coy. Ltd" previously.
