Gustavus Sessinghaus (November 8, 1838 – November 16, 1887) was aU.S. Representative from the State ofMissouri.

Sessinghaus was born on November 8, 1838 in Köln (Cologne), North Rhine-Westphalia, then part ofPrussia. After pursuing preparatory studies in Germany, he immigrated to the United States and settled inSt. Louis, Missouri, a city with a majority German speaking population, where he worked in the milling business. During theCivil War, he served as a private in Company A, Fifth Regiment, of theUnited States Reserve Corps, Missouri Volunteer Infantry. After the war, Sessinghaus became politically active as a member of theRepublican Party. From 1878 to 1880 he served as a member of the St. Louis School Board.

In the 1880 congressional election, he was defeated by DemocratRichard Graham Frost in Missouri's third district. Sessinghaus, however, appealed against the outcome of the election. Congress did not decide in his favor until the penultimate day of the legislative period, on March 2, 1883. Thus, he was only able to serve in the Forty-seventh Congress for two days (March 2, 1883 – March 3, 1883). He was an unsuccessful candidate for reelection to the Forty-eighth Congress. After leaving the U.S. House of Representatives, Sessinghaus continued his work as a miller. He died inSt. Louis, Missouri, on November 16, 1887, and was interred atBellefontaine Cemetery.
