The Pla-Mor Ballroom was a multi-purpose event center in Kansas City, Missouri, at 3142 Main Street, directly south of the Union Hill neighborhood.

[3] Beneath the ballroom were facilities for bowling and billiards while an ice rink was built in an adjacent building.

At the time it was the largest indoor pool west of the Mississippi River and helped the venue remain a popular attraction for the rest of the decade.

With dwindling attendance and the loss of the Kansas City Royals hockey team in 1951, the Ballroom was closed by the end of the year.

The building remained untouched for 20 years before it was demolished to make room for a car dealership.
