That's Life is the 71st solo studio album by Willie Nelson. It was released on February 26, 2021, by Legacy Recordings. A tribute to Frank Sinatra, it represents the second volume of Nelson's Sinatra collection, following 2018's My Way.

Produced by Buddy Cannon and Matt Rollings, it was mainly recorded on Capitol Studios, the original studio used for several of Sinatra's recordings. Additional tracks were recorded at Nelson's Pedernales studio. The release was mixed by engineer Al Schmitt, featuring string and brass arrangements. The cover of the album features a painting of Nelson evoking the cover of Sinatra's In the Wee Small Hours.

That's Life was nominated for the 2022 Grammy Award for Best Traditional Pop Vocal Album.
