The Dominican House of Studies is a Catholic institution in Washington, DC, housing both the Priory of the Immaculate Conception, a community of the Province of St. Joseph of the Order of Preachers (Dominicans), and the Pontifical Faculty of the Immaculate Conception, an ecclesiastical faculty of theology.

The Dominican House of Studies is located in Washington, D.C., on Michigan Avenue NE, directly across from The Catholic University of America.

The building was initially called the College of the Immaculate Conception and located on what was then Bunker Hill Road NE.

On June 19, 1903 District of Columbia Engineer Commissioner Col. John Biddle recommend a permit be issued, and construction could finally commence.

The Thomist is a refereed peer-reviewed Catholic theological and philosophical journal published by the Pontifical Faculty of the Immaculate Conception and the Dominican Fathers Province of St. Joseph.

In 2013, Dominicana Records and the student friars of the Dominican House of Studies in Washington, D.C., released their first album: In Medio Ecclesiae.
