A new club badge was introduced in 1971, featuring a more modern design that, with modifications, is still in use. 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 left): 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 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, with the colours being modified to the club colours of black and white in 2009 (see top of page). In July 2012, the club announced intention to show only the iconic Ram on future shirts, rather than the full club logo. In July 2013, this traditional Ram became the club's full logo again.
