The 2019 Worlds Collide was the inaugural Worlds Collide professional wrestling streaming event produced by WWE. It was held for wrestlers from the promotion's NXT, NXT UK, and 205 Live brand divisions. The event took place on January 26 and 27, 2019, at the Phoenix Convention Center in Phoenix, Arizona as part of that year's Royal Rumble weekend. The event aired on tape delay on the WWE Network as one single event on February 2, 2019.

The event featured the 15-man Worlds Collide tournament, with the wrestlers being equally divided amongst the NXT, NXT UK, and 205 Live rosters. The prize was a championship match of the winner's choice. The tournament was won by NXT's Velveteen Dream, who chose to challenge Johnny Gargano for the NXT North American Championship.
