William Christoph of Hesse-Homburg (13 November 1625, Ober-Rosbach – 27 August 1681, then in Bingenheim, now in Echzell) was the second Landgraf of Hesse-Homburg (then known as "Landgraf of Bingenheim") during 1648–1669.

He was the third (second surviving) of five sons of Frederick I, Landgrave of Hesse-Homburg, and succeeded his brother Ludwig I as Landgrave in 1643, but his mother was regent until 1648.

In 1669, he sold Homburg to his younger brother George Christian, but retained Bingenheim (Landgrave of Hesse-Homburg-Bingenheim). George Christian died without heirs, and their youngest brother succeeded as Frederick II, Landgrave of Hesse-Homburg.
