Francesco Maria Richini (also spelled Ricchini) (9 February 1584 – 24 April 1658) was an Italian Baroque architect.
After a stint in Rome, he became capomastro under the main architect of the Cathedral of the city, Aurelio Trezzi, in 1605.
In Richini he found a deviation to the Baroque, as exemplified by his churches of Santa Maria alla Porta and of San Giuseppe.
This small church in central Milan (consecrated 1616) has a highly decorated facade (finished 1630) with volutes.
He designed the "Altar of Our Lady of the Assumption" in the Como Cathedral, a work that lasted several decades and was completed in 1686.
