My Own Private Oshawa is a theatrical play written and performed by Jonathan Wilson, which premiered in 1996. A one-man show taking place aboard a GO Train in which Wilson is travelling home from Toronto to Oshawa for a visit, the show is performed as a monologue about his childhood experiences as a repressed and closeted gay kid, and the impact of his more flamboyantly gay friend Gordon on his sense of self. The ultimate purpose of the trip, to attend Gordon's funeral following his death of AIDS, is revealed only at the end of the play.

The play was staged for the first time in July 1996 at the Toronto Fringe Festival, where it was one of the major hits of the festival; due to its popularity, it was later remounted by Tarragon Theatre in the fall. The Tarragon production received two Dora Mavor Moore Award nominations (Small Theatre division) in 1997, for Outstanding New Play or Musical and Outstanding Performance by a Male (Wilson).
