The Plaza at Harmon Meadow is a shopping complex in the Meadowlands of Secaucus, New Jersey, approximately six miles from New York City.

The Plaza, which Hartz refers to as a “mixed-use community”, encompasses 175 acres (0.71 km), and consists of over 3,500,000 square feet (330,000 m) of hotel, office, retail, and restaurants space. It was purchased by Howard Michaels's Carlton Group in 2015. It was built in 1981.
