I Am My Own Wife is a play by Doug Wright based on his conversations with the German antiquarian Charlotte von Mahlsdorf. The one-person play premiered Off-Broadway in 2003 at Playwrights Horizons. It opened on Broadway later that year. The play was developed with Moisés Kaufman and his Tectonic Theater Project, and Kaufman also acted as director. Jefferson Mays starred in the Broadway and Off-Broadway productions, playing some forty roles. Wright received the 2004 Pulitzer Prize for Drama for the work.

A solo performance, sometimes referred to as a one-man show, one-woman show, or one-person show, features a single person telling a story for an audience, typically for the purpose of entertainment. This type of performance comes in many varieties, including autobiographical creations, comedy acts, novel adaptations, vaudeville, poetry, music and dance. In 1996, Rob Becker's Defending the Caveman became the longest-running one-person play in the history of Broadway theatre.
