Grace Reformed Church is a historic church building in Northwest, Washington, D.C. A notable member was Theodore Roosevelt, who regularly attended services there during his term as United States president. The congregation was originally organized in 1877 as a member of the Reformed Church in the United States (RCUS), which eventually merged into the United Church of Christ (UCC). Construction on the current building began in 1902, with then-Vice President Roosevelt laying the cornerstone; he also gave an address at its 1903 dedication.
