Betts House, also known as the John M. Davies House or Davies Mansion, is a mansion owned by Yale University in the Prospect Hill Historic District of New Haven, Connecticut. Completed in 1868 and designed by Henry Austin, it was sold to Yale in 1972 and is now home to the Yale Center for the Study of Globalization.

When built, the 21,000-square-foot (2,000 m2) square foot mansion was the largest single-family home in New Haven. In 1947, it was converted into the home of the new Culinary Institute of America, but fell into disuse for four decades after being acquired by Yale. Considering it the best example of Second French Empire Revival architecture in the city, preservationists and students stopped the university from demolishing it in the 1990s. In 2002, the building was extensively renovated and put back into use.
