Southwest Plaza is an enclosed shopping mall in unincorporated Jefferson County, Colorado, immediately south of Denver.

Littleton, Colorado is commonly indicated in the mall's postal address because its ZIP code is primarily associated with that city, which lies some two miles east.

The anchor stores are Dillard's, Dick's Sporting Goods, Round 1 Entertainment, and JCPenney.

In 1983, the mall opened with The Denver Dry Goods Company and anchor stores May-Daniels & Fisher (May D&F), Montgomery Ward, Sears, and Joslins.

In 1998, the mall was sold by Southwest Properties Venture, a partnership between Denver developers Jordon Perlmutter, Samuel Primack, and Michael Cooper to General Growth Properties for $64 million.
