Benjamin Thomas Jacobs (born 7 June 1974), more commonly known by the stage name Max Tundra, is an English multi-instrumental musician, singer and music producer. His work is noted for its maximalist approach, which is predominantly electronic music but incorporates non-electronic styles and instruments. Jacobs' production style has been noted as an influence on the hyperpop style which became prevalent in the 2010s onwards.

Other than his full-length albums, he has also done remix work for bands of varying genres including Franz Ferdinand, Architecture in Helsinki, Kid606 and the Pet Shop Boys. In 2018, Tundra wrote and produced the comeback album by Daphne and Celeste, entitled Daphne & Celeste Save the World.
