The 2019 Crown Jewel was a professional wrestling event produced by the American company WWE. It was the second Crown Jewel and took place on October 31, 2019, at King Fahd International Stadium in Riyadh, Saudi Arabia as part of the inaugural Riyadh Season, which launched earlier that same month. The event aired via pay-per-view (PPV) and livestreaming and featured wrestlers from the promotion's Raw, SmackDown, and 205 Live brand divisions. It was the fourth event that WWE held in Saudi Arabia under a 10-year partnership in support of Saudi Vision 2030. A Crown Jewel event was not held in 2020 due to the COVID-19 pandemic, but the event returned in 2021.

Nine matches were contested at the event, including one on the Kickoff pre-show. In the main event, SmackDown's "The Fiend" Bray Wyatt defeated Raw's Seth Rollins in a Falls Count Anywhere match that could not be stopped for any reason to win the Universal Championship, which subsequently transferred the title to SmackDown. In other prominent matches, Brock Lesnar defeated Cain Velasquez by submission to retain SmackDown's WWE Championship in the opening bout, professional boxer Tyson Fury defeated Braun Strowman by countout, and Natalya defeated Lacey Evans by submission in what was the first professional wrestling women's match to take place in Saudi Arabia.

The event was met with mixed to positive reception from critics; although the tag team turmoil match, Raw's United States Championship match, the 5-on-5 tag team match, and in particular the singles match between Mansoor and Cesaro were largely praised, Lesnar vs. Velasquez and Fury vs. Strowman were near-universally panned, with the Universal Championship match receiving a polarized reception. The women's match received polarized reactions for its booking and significance, while being considered average in quality.
