The BBC 6 Music broadcaster and Pulp frontman will commission new titles about popular culture alongside editorial directors Lee Brackstone and Hannah Griffiths from January 2012.
Cocker said in a statement: "I am proud, and more than a little excited, to be asked to work with Faber in an editorial capacity.
"It is my dearest hope that we will produce some fantastic books together."
Brackstone added: "Jarvis felt like a natural fit with the Faber sensibility, both as author and editor, and I'm sure the small list of books he will develop will represent his eccentric and yet popular touch.
"We now have an excellent portfolio of authors from the pop world and our intention is to develop these relationships and continue to build a reputation as the home for exciting and original writing on music."
Cocker's editorial agreement with Faber & Faber will last for two years. The company will also publish a book of his lyrics entitled Mother, Brother, Lover on October 20.
