The 2015 Elimination Chamber (known as No Escape in Germany) was a professional wrestling event produced by WWE. It was the sixth Elimination Chamber and took place on May 31, 2015, at the American Bank Center in Corpus Christi, Texas, marking the only edition of the event to be held in May; previous and future incarnations have taken place in February (except 2020 and 2025, which both took place in March). The event aired via livestreaming, marking the first Elimination Chamber to be broadcast on the WWE Network, and it was available on pay-per-view (PPV) in various territories outside the country. It was also the first event to include a tag team Elimination Chamber match, although it is also the first event in WWE history where the Chamber did not play host to a match for a world championship or future world championship match opportunity. An Elimination Chamber event was not held in 2016, but it returned in 2017; in turn, it was the last Elimination Chamber event to be held before the reintroduction of the brand extension in July 2016 and the last event to feature the original Elimination Chamber structure that was used since 2002.

Seven matches were contested at the event, including one on the Kickoff pre-show. In the main event, Dean Ambrose defeated WWE World Heavyweight Champion Seth Rollins by disqualification. In other prominent matches, Ryback defeated Dolph Ziggler, King Barrett, Mark Henry, R-Truth, and Sheamus in an Elimination Chamber match to win the vacant WWE Intercontinental Championship, NXT Champion Kevin Owens defeated WWE United States Champion John Cena in Owens' main roster debut match, which was a non-title match, and in the opening bout,The New Day (Big E, Kofi Kingston, and Xavier Woods) defeated The Ascension (Konnor and Viktor), The Lucha Dragons (Kalisto and Sin Cara), Los Matadores (Diego and Fernando), The Prime Time Players (Darren Young and Titus O'Neil), and Tyson Kidd and Cesaro in a tag team Elimination Chamber match to retain the WWE Tag Team Championship.
