Rienzi is the Museum of Fine Arts Houston house museum for European decorative arts, situated on four acres of wooded gardens, about three miles from downtown Houston in the historic River Oaks neighborhood. 

Formerly the home of philanthropists Carroll Sterling Masterson and Harris Masterson III, Rienzi was designed by prominent Houston architect John Staub in 1952.

Opened to the public in 1999, Rienzi houses a substantial collection of European decorative arts, including paintings, furnishings, porcelain, and extensive holdings of miniatures.

Visits to the house and art collection are by docent-led tour only.
