The present paper focuses on the flora of synuralean algae from four northern provinces in Vietnam: Bac Kan, Hanoi, Ninh Binh, and Thanh Hoa. Fifty-five water bodies were studied, including territories within national parks Ba Be, Ba Vi, Cuc Phuong, Ben En, and Trang An Wetland—The World Cultural and Natural Heritage and Van Long Wetland Nature Reserve. Samples were obtained from natural lakes and wetlands, artificial reservoirs and ponds, and small temporary water bodies. Electron microscopy allowed for the discovery of 39 taxa, 37 of which belonged to the genus Mallomonas and two to the genus Synura. Six taxa of the genus Mallomonas and two taxa from the genus Synura were not identified to the lower rank. Five taxa are reported for the first time in Vietnam. The most diverse flora was observed in natural protected water bodies. Eutrophic and hypereutrophic water bodies, which were prevalent in the study area, had a reduced number of selected species.
