The Honorable Congress of the State of Sonora () is the legislative branch of the government of the State of Sonora. The Congress is the governmental deliberative body of Sonora, which is equal to, and independent of, the executive. The Congress is unicameral and consists of 33 deputies. 21 deputies are elected on a first-past-the-post basis, one for each district in which the entity is divided, while 12 are elected through a system of proportional representation. Deputies are elected to serve for a three-year term. Since its installation the congress has been renewed 61 times, hence the current session of the Congress of Sonora (whose term lasts from 2018 to 2021) is known as the LXII Legislature.
