The pageant is held annually with representation of several municipalities.

Since 2023, the State directors of Miss Mato Grosso are, Muryllo Lorensoni and Nadeska Calmon.

Before 1979, Mato Grosso and the now State of Mato Grosso do Sul were one state, because of this women from the now State of Mato Grosso do Sul were able to compete in Miss Mato Grosso due to the two being in one.
