Traub-Bin Vulf (Wulf) Solomonovich (1902 — ?) — political activist.

Vulf Traub-Bin graduated from a gymnasium in 1925 and subsequently worked in various occupations in Lithuania. In 1922–1928, he was one of the leaders of the Zionist organization *“Poalei Zion.”

In 1925, he was arrested for distributing communist literature among soldiers and was imprisoned in Panevėžys and Kaunas prisons, from which he was released under an amnesty. Following the coup d'état in Lithuania in 1927, he emigrated to Riga.

In Riga, he participated in the activities of Lithuanian political émigrés and was also involved in the transport of illegal literature into Lithuania. For this, he was sentenced in 1928 to four years' imprisonment but spent five and a half years in prison.

After his release, he emigrated to the USSR, where he worked at an automobile plant and later in metro construction. In 1937, he was sentenced to five years' imprisonment, and in 1950 — to ten years. He was subsequently rehabilitated.
