Concordia Log Cabin College is a historic site in Altenburg, in Perry County, Missouri. The structure is a log building under a protective shelter situated in the Trinity Lutheran Church maple grove. It served as the first college for the Lutheran Church–Missouri Synod and was first Lutheran college west of the Mississippi River. Today, it commemorates the German Lutheran migration of 1838–1839 and the founding of the Lutheran Church–Missouri Synod, and features two log cabins from that era. The building was listed on the National Register of Historic Places in 1978.
