Jack Black -- Welcome to Disneyland!

Jack Black didn't just help pay for a school marching band to travel to Disneyland so they could perform in a parade -- he showed up to cheer them on!

As TMZ first reported, Black donated $10,000 to the Tonasket High School Band from Tonasket, Washington to help cover their travel expenses to the Happiest Place on Earth.

The band performed in the Main Street USA parade and got to meet their generous benefactor afterward.

That rocks.
