Nga Sơn is a district (huyện) of Thanh Hóa province in the North Central Coast region of Vietnam.

These include Từ Thức grotto, Tien Pagoda (Chùa Tiên), and legends referring to Mai An Tiêm who, the story goes, was exiled to the then uninhabited islands, now known as Nga Son and Thanh Hoa.

[1] The district is located northeast of the Thanh Hóa province.

With a coastline about 20 kilometers (12 mi) long, Nga Sơn annually encroaches into the sea some 80–100 kilometers (50–62 mi) per year due to alluvium deposits from the Red and Day Rivers.
