The Congress is the governmental deliberative body of Tabasco, which is equal to, and independent of, the executive.

It is located in front of the Plaza de Armas, in the historic center of the city of Villahermosa, capital of the state.

21 deputies are elected on a first-past-the-post basis, one for each district in which the entity is divided, while 14 are elected through a system of proportional representation.

Deputies are elected to serve for a three-year term.
