The Lehigh Valley is home to many retail establishments. The largest retail area of the Lehigh Valley is the Pennsylvania Route 145/MacArthur Road Corridor, just north of Allentown, and is anchored by the Lehigh Valley Mall.

In October 2006, another Valley-based shopping mall, The Promenade Shops at Saucon Valley, opened. The Promenade Shops is located off Route 309 in Upper Saucon Valley Township. It is roughly half the size of the Lehigh Valley Mall, but features more upscale stores.
