Catherine Tate's Nan (simply referred to as Nan on-screen) is a BBC One spin-off series of specials which follows the character of Joanie Taylor (Catherine Tate) from the original sketch comedy series The Catherine Tate Show. When the initial series ended in 2007, a Christmas Special was broadcast in 2009, Nan's Christmas Carol, which is now established as the first episode of the Nan specials, and was followed by three subsequent specials in 2014 and 2015 under the title Nan.
