Rihan forest, Nature reserve and protected forest in the northern West Bank, near Jenin

Rihan Forest is a protected woodland in the northern West Bank, northwest of Jenin near the Green Line and the village of Umm ar-Rihan. Its dense canopy of common oak, Palestine oak, terebinth and carob covers hilly terrain reaching 412 metres above sea level, with two small seasonal pools, one beside the forester's house.

The forest was given official protection status in 1991, which secured its conservation for future generations. It was later nominated as part of a broader area for the UNESCO Tentative World Heritage List.

The forest is named after Umm ar-Rihan, the Palestinian village beside it, whose name means "Mother of the Basilica". The village began in the late 19th century as a seasonal farming outpost of Yabed and has been permanently inhabited since 1922. Charcoal burning was long a local trade; the nearby town Umm al-Fahm takes its name, "Mother of Charcoal", from it.

The forest is best explored on foot using the marked trails that wind through the woodland and open terrain. Sturdy shoes and enough water are a good idea, particularly in summer when the heat can be intense.

The forest survived because its stony ground was unfit for cultivation and too far from villages for herding, so grazing and tree felling were banned and a guard's house was built at its heart. In 2012 the Palestinian delegation to UNESCO put the woodland on the Tentative World Heritage List.
