Hor Haggidgad (Hebrew: חֹר הַגִּדְגָּד, Ḥōr Ha-Giḏgāḏ, 'cave of the Gidgad') is one of the stops of the Israelites on the Exodus journey. It is mentioned in Book of Numbers 33:32-33 as a place where the Israelites stopped during the Exodus, probably meaning 'cave of GidGad/GudGod'. it is called Gudgodah in Deuteronomy 10:7. Its location is uncertain but has been identified as possible near Wadi Hadahid or Wadi Ghadhaghedh in the Eastern Sinai although some see this as etymologically impossible.
