These are the winners and nominees for the Tony Award for Best Costume Design. The award was first presented in 1947 and included both plays and musicals. In 1961, and since 2005 each genre is represented in its own category.
In 2010, Santo Loquasto received a nomination for Best Costume Design for a Musical for Ragtime. Loquasto, who was previously nominated for the same show in the same category in 1998, was later disqualified because the designs were predominantly recycled work from the earlier production. No replacement was made for the nomination.
