Henry V of Honstein-Sondershausen

Henry V (III) of Honstein (c. 1290–1356) was count of Honstein-Sondershausen in the Thuringian Harz, son of Count Henry III and Jutta of Ravensberg. He ruled Sondershausen from 1312 and around 1319 married Matilda of Brunswick-Göttingen.

He also held several pledged Thuringian lordships. His daughters Agnes and Elizabeth married Schwarzburg counts, and leaving no son, Henry died after 24 April 1356, whereupon Sondershausen passed to the Schwarzburgs.
