What is the name of Coco’s opening short film shown before the feature in theaters?

The short film shown before Coco in its original theatrical release was Olaf’s Frozen Adventure.

Olaf’s Frozen Adventure is a 2017 animated short from Walt Disney Animation Studios. It follows Olaf and Sven as they search for holiday traditions for Anna and Elsa after discovering that the sisters have no family tradition of their own.

The short was unusual as a theatrical companion because it runs much longer than many customary animated shorts. It was attached to Coco in theaters before later being released separately on television and home media.

This pairing is sometimes confused with Pixar shorts such as Lava, Piper, or Sanjay’s Super Team. Those shorts were associated with other Pixar theatrical releases, whereas Olaf’s Frozen Adventure accompanied Coco.
