The Lyngholman Nature Reserve (Norwegian: Lyngholman naturreservat) is located on Finnøya island in the municipality of Ålesund in Møre og Romsdal county, Norway.

The bay that the site encompasses has many beach meadows, shallow coves, small islands and large tidal areas.

The landscape is undisturbed, and it is hilly with heather fields, marshes, and pastures around the beach meadows.

The bay is a nesting ground for waders, and a grazing and overwintering site for other wetland species.

The reserve is one of six natural areas that were included in the Harøya Wetlands System Ramsar site, which was established in 1996.
