Does Deadpool 2 Have a Post-Credit Scene?

Yes, there are extra scenes during, or after, the end credits of Deadpool 2.

Long story short: stay to the end of the credits.

The credits begin with story-related crayon drawings of the main cast/crew, lasting for 1:45 minutes.

After this, there is a must-see extra scene. Seriously, if anyone tries to leave the theater, you drag them back.

After the mid-credits scene, there isn't anything else until near the very end of the credits, when there is a hugely humorous musical extra (audio only). However, many people have reported that this extra song didn't play in their showing.

The credits run for approximately 9 minutes.
