The 2018 Elimination Chamber 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.
