Jeffrey and Sloth is a Canadian children's book by Kari-Lynn Winters and Ben Hodson.

Jeffrey and Sloth first appeared in a 2004 issue of Chameleon, a children's magazine published by the University of British Columbia, as "Jeffrey's Wor(l)ds Meet Sloth".

Orca selected this book as one of 9 out of 1600 manuscripts chosen for publication in 2007.

The book has come to life beyond the page, as a literacy play performed by Tickle Trunk Players in schools in Vancouver, Calgary, and Toronto.

Jeffrey struggles against the strong-willed Sloth, in the process telling a tale and completing his homework.
