Tarvi Thomberg (born May 10, 1982) is a retired amateur Estonian Greco-Roman wrestler, who competed in the men's light heavyweight category.
Thomberg represented his nation Estonia at the 2004 Summer Olympics, and has also held three Estonian and Nordic championship titles in the light heavyweight division.
Delivering a mediocre, yet a disappointing performance in the preliminary pool, Thomberg lost all of his matches against Ukraine's Oleksandr Daragan, Bulgaria's Vladislav Metodiev, and Turkey's Hamza Yerlikaya, who was seeking to defend his Olympic title from Sydney four years earlier, without receiving a single point.
