St. Luke's Episcopal Church is a historic Episcopal church located on Bedford Road in Katonah, New York, United States. It is a Tudor Revival structure dating to the early 1920s, housing a congregation restarted in the early 20th century. The church building was designed by Hobart Upjohn, third in the family of American architects by that name. The original parish house, moved from its location along with most of Katonah in the late 19th century, has been demolished, but the church itself remains intact. In 2001 it was added to the National Register of Historic Places.
