One Last Time: An Evening with Tony Bennett and Lady Gaga is a television special by American singers Tony Bennett and Lady Gaga. It originally aired on November 28, 2021, on CBS while being simulcast on Paramount+. Consisting of select duets and solo performances, it was part of the promotion of their second collaborative studio album, Love for Sale, released on September 30, 2021. A celebration of Bennett's 95th birthday, the special was recorded on August 3 and 5, 2021, when Bennett and Gaga presented a pair of shows at Radio City Music Hall in New York City. They were Bennett's final public performances, as he retired shortly after from performing live due to his health condition.

The duo was joined on stage by a 41-piece orchestra and musicians related to both artists. Before its release, backstage content of the shows were documented in CBS' television news magazine 60 Minutes, while their performance of "Anything Goes" broadcast on The Late Show with Stephen Colbert as a preview on November 23, 2021. When aired, the special was watched by 6.38 million viewers and had a positive critical response, receiving four nominations at the 74th Primetime Emmy Awards.
