The 2018 Hell in a Cell was the 10th annual Hell in a Cell professional wrestling pay-per-view and livestreaming event produced by WWE. It was held for wrestlers from the promotion's Raw and SmackDown brand divisions. The event took place on September 16, 2018, at the AT&T Center in San Antonio, Texas. Previously, Hell in a Cell was held annually in October, thus the 2018 event was the first to not have occurred during that month. The event returned to the October slot the following year, but in 2021, the event series was moved up to June.
