Viktor Berg (born October 8, 1977 in Edmonton, Alberta) technically in Estonia and Finland count Viktor Berg de Sangaste, is a Finnish-origin professional male squash player who represented Canada during his career.

His grandfather fled from the early 1940s problems (and coming communist rule) in the Baltic countries, and settled to Canada, where he served in the grain development institute's research.

He in his turn was a grandson of the Finnish baroness Maria Bruun and count Fredrik Berg, the famous improver of Baltic agriculture, particularly rye.

Ancestors include also baron Theodor Bruun, Minister Secretary of State of the Grand Duchy of Finland.
