Wadi Saham is a seasonal watercourse in the Hajar Mountains of Fujairah, in the United Arab Emirates.

It is notable for its petroglyphs, including a single rock bearing 26 petroglyphs across four faces.The Wadi Saham is located to the West of Fujairah City and consists mainly of a rocky wadi floor with scree and mountain walls.

The largest petroglyph assemblage in the wadi is focused on a single rock, to the side of the road, with a large number of horse riders depicted, as well as geometric shapes such as the letter I and cruciform images.

The petroglyphs have to a large extent been preserved by a natural bacterial deposit, known as desert varnish.
