Çağlayan (literally "Waterfall") is a neighbourhood of the municipality and district of Ortahisar, Trabzon Province, Turkey.
It is on Turkish state highway D.885 which connects Trabzon to hinterland (and Sümela Monastery).
In 1946 owing to its situation along the valley, it was founded as a common market place of the neighbouring villages.
It quickly flourished and in 1969 it was declared a seat of township.
