The 2018 Elimination Chamber (known as No Escape in Germany) was the eighth Elimination Chamber professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was held exclusively for wrestlers from the promotion's Raw brand division. The event took place on February 25, 2018, at the T-Mobile Arena in the Las Vegas suburb of Paradise, Nevada. It was the final Raw-exclusive pay-per-view under the second brand split as following WrestleMania 34 in April, WWE discontinued brand-exclusive pay-per-views. The 2018 event was also the first to feature a seven-man Elimination Chamber match, the first event to include a women's Elimination Chamber match, and the first Raw-exclusive pay-per-view since the 2016 reintroduction of the brand extension to not feature any cruiserweight division matches.

Six matches were contested at the event, including one on the Kickoff pre-show. In the main event, Roman Reigns won the first-ever seven-man Elimination Chamber match to become the number one contender against Brock Lesnar for the Universal Championship at WrestleMania 34. In other prominent matches, Alexa Bliss retained the Raw Women's Championship in the first-ever women's Elimination Chamber match, and Asuka defeated Nia Jax to extend her undefeated streak and to prevent Jax from being added to her WrestleMania 34 championship match. The event was also notable for Ronda Rousey signing her Raw contract, where she had a confrontation with Chief Operating Officer Triple H and Raw Commissioner Stephanie McMahon, which was the former's first appearance since the night after Survivor Series in November 2017.
