Namtok Mae Surin National Park (Thai: อุทยานแห่งชาติน้ำตกแม่สุรินทร์) is a national park in Mae Hong Son Province, Thailand. Home to mountains, waterfalls and caves, the park is best known for its namesake Mae Surin waterfall.
Namtok Mae Surin National Park is located east of Mae Hong Son town in Mae Hong Son and Khun Yuam districts. The park's area is 399 square kilometres (154 sq mi). The highest point is Doi Pui peak at 1,700 metres (5,600 ft). Doi Pui is part of the Thanon Thongchai Range, whose various peaks within the park range from 300 metres (980 ft) to 1,700 metres (5,600 ft).
In 1981, Namtok Mae Surin was designated Thailand's 37th National Park.
The park's main attraction is its namesake waterfall, Mae Surin, a single-tier waterfall 180 metres (590 ft) in height. Another large waterfall is Pa Bong, a two-tier waterfall with a height of 30 metres (98 ft). Many of the park's streams eventually join the Pai River, which flows through the park. Nam Hu Haichai Cave is notable for being the site of a water jet erupting from the cave's interior walls at a regular interval of every 25 minutes.
Namtok Mae Surin features sparse dry dipterocarp forest and more dense evergreen forest. Tree species include teak and upland pine. The park is home to a rare and indigenous lady slipper orchid.
