Upper Solaiyar or Upper Sholayar Dam (சோலையாறு Solaiyaaru) is located 20 km (12 mi) from Valparai, a hill station in the Anaimalai Hills of the Coimbatore district, Tamil Nadu India. As it is a part of the hydroelectric project of Tamil Nadu, special permission is required to visit the dam.

Valparai is located 64 km (40 mi) from Pollachi and 104 km (65 mi) from Chalakudy, Kerala. The nearest railway station is Pollachi.

The Solaiyar dam is a vital reservoir under the Parambikulam Aliyar Project and has a water storage capacity of 160 ft (49 m). The reservoir's overflowing waters are let into the Parambikulam Reservoir through the saddle dam.[2]

It was constructed by a team working under K. Gopalswamy Mudhaliar, the most popular engineer in that area.
