Vasil'evbreen is a glacier in Sørkapp Land at Spitsbergen, Svalbard. It has an extension of about twenty kilometers, with several tributary glaciers. It is named after Russian astronomer Alexandr Semenovich Vasil'ev.[1][2] The glacier has a wide front facing towards the eastern shore of Spitsbergen, including the bay of Isbukta.[3] The southern part of Vasil'evbreen is called Randbreen, located north of Istoppane and Dumskolten, and south of Søre Randberget.[1]
