The Robert Treat Center is an office and hotel complex in Newark, New Jersey, United States.

One building originally opened as the Robert Treat Hotel in 1916.

The landmark was later converted to an office building after the construction of a newer hotel next to it.

The adjacent buildings are located at Military Park near the New Jersey Performing Arts Center, One Theater Square and New Jersey Historical Society.
