Henry III, Landgrave of Upper Hesse, German noble (d. 1483)
Henry III, Landgrave of Upper Hesse, called "the Rich" (15 October 1440 – 13 January 1483) was the second son of Louis I of Hesse and his wife Anna of Saxony.

Upon the death of his father Louis I in 1458, Henry received Upper Hesse and his brother Louis II received Lower Hesse. He succeeded to the title of Landgrave of Hesse-Marburg in 1458. His nickname "the Rich" is indicative of his fortune in territory and tolls on the Rhine received by his marriage to Anna, daughter and heir of Philipp, the last Count of Katzenelnbogen and his wife Anne of Württemberg.
