The 2015 Fastlane was the inaugural Fastlane professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It took place on February 22, 2015, at the FedExForum in Memphis, Tennessee. Fastlane replaced Elimination Chamber in the February slot of WWE's PPV event calendar; Elimination Chamber itself was pushed back to May for 2015.

Seven matches were contested on the main card with no matches on the Kickoff pre-show. In the main event, Roman Reigns defeated Daniel Bryan to retain his WWE World Heavyweight Championship shot against Brock Lesnar at WrestleMania 31. In the penultimate match, Rusev defeated John Cena via technical submission to retain the WWE United States Championship. In another prominent match, Bad News Barrett retained the WWE Intercontinental Championship against Dean Ambrose. Also at the event Triple H had a "face-to-face" confrontation with Sting.

The event received 46,000 buys (excluding WWE Network views), down from the Elimination Chamber 2014 figure of 183,000 buys, which predated the launch of the WWE Network.
