Which musical holds the record for the most Tony Awards won by a single production?

The Producers holds the record for the most Tony Awards won by a single production, with 12 victories.

The record came at the 55th Tony Awards in 2001, when the Broadway musical won 12 awards from 15 nominations. It surpassed the previous record of 10 Tony wins held by Hello, Dolly! The Producers won Best Musical and awards recognizing its performances, creative team, book, score, direction, choreography, and design.

Adapted from Mel Brooks's 1968 film, the stage musical follows the scheming producer Max Bialystock and his anxious accountant Leo Bloom as they attempt to profit from a deliberately doomed show. Brooks wrote the music and lyrics, while Thomas Meehan and Brooks shared credit for the book. Nathan Lane and Matthew Broderick starred in the original Broadway production.

Hamilton came closest among later blockbuster musicals, winning 11 Tonys in 2016, but it did not break The Producers' record. The Producers also ran for 2,502 performances on Broadway, making its awards haul part of a larger landmark success rather than a one-night curiosity.
