The Thomistic Institute is an academic institute of the Pontifical Faculty of the Immaculate Conception at the Dominican House of Studies, a Catholic pontifical faculty run by the Order of Preachers (Dominicans) located in Washington, D.C. Founded in 2009, its name derives from the order's heritage of Thomas Aquinas, as the Thomistic tradition influences the institute. The institute was initially founded as an academic research institute of the Pontifical Faculty but evolved into a network of campus chapters at universities throughout the United States, England, and Ireland that sponsor lectures on theology, philosophy, ethics, and politics. As of 2018, the institute had chapters at around 60 universities. Counted among its past speakers are Scottish philosophers Alasdair MacIntyre and John Haldane, French philosopher Remi Brague, American philosopher Robert Sokolowski, English philosopher Sir Roger Scruton, Australian philosopher Mark Johnston, the Theologian of the Pontifical Household Wojciech Giertych, and the United States Supreme Court Justice Neil Gorsuch. In addition to individual lectures, the Institute has co-sponsored academic conferences with Harvard Law School, Yale University, New York University, Georgetown University, and Notre Dame University, among others. It also organizes an annual conference on Thomistic philosophy at Mt. St. Mary's College in Newburgh, New York and an annual Thomistic Philosophy and Natural Science conference for faculty and graduate students in the experimental sciences and philosophy, held in Washington, D.C.
