The Washington D.C. Temple is the 18th constructed and 16th operating temple of the Church of Jesus Christ of Latter-day Saints. It is located in Kensington, Maryland, United States, just north of Washington, D.C., near the Capital Beltway. The temple was dedicated in 1974 after an open house that attracted over 750,000 people, including several international dignitaries. The temple was the first temple built by the church east of the Mississippi River since 1846, when the original Nauvoo Temple was dedicated.

In the Church of Jesus Christ of Latter-day Saints, a temple is a building dedicated to be a House of the Lord. Temples are considered by church members to be the most sacred structures on earth.
