Michael Dunn was an American actor and singer with dwarfism. He was nominated for the Tony Award for Best Featured Actor in a Play for The Ballad of the Sad Café, and for the Academy Award for Best Supporting Actor in Stanley Kramer's Ship of Fools, but best remembered for a recurring role as antagonist Dr. Miguelito Quixote Loveless in the 1960s television adventure series The Wild Wild West. He inspired a number of later actors with dwarfism, including Zelda Rubinstein, Eric the Actor, and Mark Povinelli.

The Tony Award for Best Featured Actor in a Play is an honor presented at the Tony Awards, a ceremony established in 1947 as the Antoinette Perry Awards for Excellence in Theatre, to actors for quality supporting roles in a Broadway play. Honors in several categories are presented at the ceremony annually by the Tony Award Productions, a joint venture of The Broadway League and the American Theatre Wing, to "honor the best performances and stage productions of the previous year."
