Philip of Hesse-Philippsthal (14 December 1655 - 18 June 1721) was the son of William VI, Landgrave of Hesse-Kassel and Hedwig Sophia of Brandenburg. He was the first landgrave of Hesse-Philippsthal from 1663 to 1721 and the founder of the fifth branch of the house of Hesse.
In 1680, Philip of Hesse-Philipsthal married Catherine of Solms-Laubach (1654–1736) (daughter of Count Charles Otto of Solms-Laubach). They had 8 children:
Philip of Hesse-Philippsthal belonged to the Hesse-Philipsthal branch - this fifth branch was issued from the first branch of the House of Hesse, itself issuing from the first branch of the House of Brabant.
After the abdication of landgrave Ernest of Hesse-Philippsthal (1846-1925) in 1868, the Hesse-Philippsthal branch perpetuated itself through the sixth branch of Hesse-Philippsthal-Barchfeld, currently represented by William of Hesse-Philippsthal (1933-).
