James Mark Cornette is an American author and podcaster who has previously worked in the professional wrestling industry as an agent, booker, color commentator, manager, photographer, promoter, trainer, and occasional professional wrestler. Cornette is widely considered to be one of the greatest managers in wrestling history by fans and publications, as well as industry personnel. Cornette currently hosts two podcasts along with co-host and producer Brian Last—The Jim Cornette Experience and Jim Cornette's Drive-Thru— with the latter being the most-played wrestling podcast as of February 2024 and both being among the most popular wrestling podcasts of all time.

In professional wrestling, a manager is a supporting character paired with a wrestler for a variety of reasons. A woman accompanying, or "seconding", a male wrestler to a match is sometimes referred to as a valet.
