The logo will appear on the Rams' new Adidas kit , which is due to go on sale in late July or early August. A circular surround replaces the previous yellow banner beneath the Ram, and the date the club was founded is also included.

Like most old football clubs, Derby County did not initially have any badge displayed on their shirts. Their first badge was introduced in 1924. The badge consisted of a circular shield spilt into three equally-sized sections, representing the club, its fans and the area, in three equally-sized sections, all containing items traditionally associated with the city of Derby: a Tudor rose and a crown in one section,

By 1934, another badge had been introduced. This time it was a traditionally-shaped shield, again with three sections. The buck in the park had been removed and the rose and the crown had been split up and now occupied a section each. The ram's head also remained and was now given the largest section of the shield. The badge never appeared on the players' shirts.

The shield was modified in 1946 when the rose and crown were removed and replaced with the letters DC (Derby County) and FC (Football Club) respectively. The badge, right, was featured on to the player's shirts from its introduction onwards, though the ram's head on its own was used from the late 1960s (the full shield, however, remained the club's official logo).

A new club badge was introduced in 1971, featuring a more modern design that, with modifications, is still in use today. The badge was initially consisted of a stylised white ram facing left. The badge was first modified slightly in 1979 to include the text 'Derby County FC' under the ram (though the ram remained on its own on away kits).

In 1982 the ram turned to face to the right and the text under it was removed. The ram was surrounded by a wreath of laurel and the text 'Centenary 1984-1985' was printed underneath for the club's centenary season.

The laurel was removed and the text reading 'Derby County FC' returned from the next season.

In 1993, the ram faced left again and the text was removed once more. From 1995, the ram faced right and was enclosed in a diamond, with a gold banner reading 'Derby County FC' underneath and the text '1884' (the year of the club's foundation) underneath that.

The design was changed again in 1997 (see right): the ram faced now left and the golden banner now simply read 'Derby County'; the diamond and year of formation were removed.

A decade later, in 2007, the badge was modified again (to the one seen at top of this article), with the ram (still facing left) and the text 'Est. 1884' now in the middle of a circular frame featuring 'Derby County Football Club' in gold lettering.
