[3] Tied 2–2 on aggregate, Atlético Paranaense won 4–3 on penalties, winning the tournament for the first time in their history.

Atlético Paranaense also automatically qualified for the group stage of the 2019 Copa Libertadores.

The final was played on a home-and-away two-legged basis, with the higher-seeded team (Atlético Paranaense) hosting the second leg.

The away goals rule was not applied, and extra time would be played if the aggregate score was tied after the second leg.

If the aggregate score was still tied after extra time, a penalty shoot-out would have been used to determine the winner.
