The Iowa District West is one of the 35 districts of the Lutheran Church - Missouri Synod (LCMS), and covers the western half of the state of Iowa including the state capital, Des Moines; the rest of the state forms the Iowa District East. The Iowa District West includes approximately 174 congregations and missions, subdivided into 19 circuits, as well as 43 preschools and 10 elementary schools. Baptized membership in district congregations is over 65,000.

The Iowa District West was formed in 1936 when the Iowa District (created in 1879) was divided in half. District offices are located in Fort Dodge, Iowa; the Rev. Paul Sieveking has been the district president since August 2000, and was reelected to a third term in 2006. Delegates from each congregation meet in convention every three years to elect the district president, vice presidents, circuit counselors, a board of directors, and other officers; the last convention was held on June 18-21, 2006, and the next will be held in 2009.
