Seowoncheon (Korean: 서원천) is a stream which flows through Iseo-myeon in Cheongdo County, southern North Gyeongsang Province, South Korea. It is a third-level tributary of the Nakdong River, as it flows into the Cheongdocheon, which in turn flows into the Miryang River, which in turn flows into the Nakdong. It rises from the slopes of Bonghwasan, which stands on the border of Cheongdo County and Daegu.

The Seowoncheon takes its name from two seowon near its course. These are the Heungseon Seowon and Geumho Seowon. Seowon were the principal form of private education during the Joseon period.

The Seowoncheon is best known for the Cheongdo Bullfighting Festival, which is held once a year on its broad and sandy banks.
