Mob Boss is a 1990 direct-to-video Mafia-themed comedy film directed by Fred Olen Ray and starring Eddie Deezen, Morgan Fairchild, Teagan Clive and William Hickey.

Unfortunately for the family, Tony (Eddie Deezen) is a wimpy nerd with no idea of the true nature of his father's business.

As Monk tries to transform the milquetoast geek into a fearsome gangster, Don Francisco attempts to overthrow him through Gina's powers of seduction, while a pair of bumbling hitmen (Brinke Stevens and Jack O'Halloran) try to bump Tony off at every turn.

The film starred Eddie Deezen who had previously worked with Fred Olen Ray on Beverly Hills Vamp.

Entertainment Weekly gave the film a "C−" rating, writing "This mostly rotten comedy from bad-movie king Fred Olen Ray (Hollywood Chainsaw Hookers) offers amazingly low-brow slapstick, but the cast has fun (especially Morgan Fairchild, of all people) and the liberal use of boingy sound effects makes for a few silly laughs".
