The Arizona Diamondbacks' 2014 season was the franchise's 17th season in Major League Baseball and their 17th season at Chase Field. The team failed to improve on their 81–81 record from 2013. As a result, they finished with a record of 64–98, placing last in the National League West and having the worst record in the major leagues. General manager Kevin Towers was fired on September 5 and replaced by Dave Stewart. On September 26, manager Kirk Gibson was also fired, ending his -year tenure as the Diamondbacks' manager. Bench coach Alan Trammell managed the final three games of the season. On October 13, Chip Hale was announced as the Diamondbacks' manager for 2015.

Regular season

March/April This season, Major League Baseball scheduled the Diamondbacks and Los Angeles Dodgers to open the season with a two-game series at the Sydney Cricket Ground in Australia. As a result, both teams began spring training earlier than usual and played abbreviated Cactus League schedules before flying to Australia for the series.
