Tobias Michael Carel Asser (28 April 1838, Amsterdam – 29 July 1913, The Hague) was a Dutch jurist, cowinner (with Alfred Fried) of the Nobel Prize for Peace in 1911 for his role in the formation of the Permanent Court of Arbitration at the first Hague peace conference (1899). He also advocated for the creation of an international academy of law, which led to founding of the Revue de Droit International et de Législation Comparée with John Westlake and Gustave Rolin - Jaequemyns, the Institut de Droit International and the creation of the Hague Academy of International Law.

He was son of Carel Daniel Asser (1813 - 85), and grandson of Carel Asser (1780 - 1836).

A research institute in the fields of Private and Public International Law, European Law and International Commercial Arbitration is named after Tobias Michael Carel Asser. This is the T.M.C. Asser Instituut, based in The Hague, Netherlands.
