The Christ Episcopal Church, at junction of 10th Ave. and Linden St. in Sidney, Nebraska, is a historic Shingle Style church that was built during 1886-87. It was listed on the National Register of Historic Places (NRHP) in 1994; the listing included the church as a contributing building and a 1950 rectory as a non-contributing building.It is significant as "one of a few remaining physical representations in the state that is closely associated with the government's attempt to integrate Native Americans into the army and consequentially adopt Euro-American social mores. The church was used by, among others, Company I, Twenty-First Infantry which was composed of Native Americans and commanded by a white officer." Company I was posted at Fort Sidney during 1892 to 1894, the period of significance designated for the church in the NRHP listing.
