Phraseang (Thai: พระแสง, pronounced [pʰrá(ʔ).sɛ̌ːŋ]) is a district (amphoe) of Surat Thani province, Thailand.

In 1899 the monthon administrator Phraya Sukhumnaiwinit (Pan Sukhum) visited the area and noticed that Lamphun was too large to administer the area efficiently, and recreated the Phrasaeng District consisting of tambons Phrasaeng and I-Pan.

[4] In 1968 King Bhumibol Adulyadej and his family made a royal visit to the district.

On that occasion the king donated a Caterpillar D4 bulldozer to the community, to aid in the development of the area.

The government sent an official named Phrasaeng Phiram to oversee construction of the district office.
