The 2023 Arizona Diamondbacks season was the franchise's 26th season in Major League Baseball and their 26th season at Chase Field in Phoenix, Arizona, as members of the National League West. They were managed by Torey Lovullo in his seventh season with the franchise. The Diamondbacks drew an average home attendance of 24,212 in 81 home games in the 2023 MLB season, the 20th highest in the league. The total attendance was 1,961,182.

On September 30, the Diamondbacks clinched a playoff spot and they faced the Milwaukee Brewers in the NLWCS. They upset the Brewers, sweeping them in two games to advance to the NLDS where they faced the Los Angeles Dodgers. They swept the heavily favored Dodgers in three games to advance to the NLCS for the first time since 2007. In the NLCS, they defeated the Philadelphia Phillies in seven games to advance to their first World Series in 22 years where they lost to the Texas Rangers in five games, earning their first World Series loss in franchise history.

The 2023 team was nicknamed "The Answerbacks" by fans and local media since they had a reputation for consistently pulling out come-from-behind wins. Diamondbacks broadcast announcer Steve Berthiaume was the first person to coin the term.

Offseason The Diamondbacks finished the 2022 season 74–88, an improvement on their 2021 record of 52–110. They finished 37 games out of 1st and missed the postseason for the fifth consecutive season.
