The Frans Hals Museum is a museum in Haarlem , the Netherlands founded in 1862.

The museum was initially located inside the former cloisters of the Dominican church located in the Prinsenhof, but in 1913 it was moved to the abandoned site of the city's orphanage. The collection contains a large number of paintings owned by the city of Haarlem: over 100 works of art confiscated from Catholic churches in 1580 after the Protestant Reformation.

Since 2018 the museum has two locations: the Hal (located in Grote Markt) and the Hof (located in Groot Heiligland).

Over 100,000 paintings were produced in Haarlem between 1605 and 1635. Not all of them have reached the present day, but this can still tell us a lot about the artistic climate that reigned in the city at that time; in fact, more art survived in that period in Haarlem than in any other Dutch city, thanks above all to Schilder's boeck published by Karel van Mander in 1604.

Among the exhibited artists, we remember: Jan van Scorel, Maarten van Heemskerck, Karel van Mander, Hendrick Goltzius, Cornelis Cornelisz van Haarlem, Frans Hals, Dirck Hals, Willem Claeszoon Heda, Pieter Claesz, Salomon de Bray, Pieter Saenredam, Salomon van Ruysdael , Adriaen Brouwer, Judith Leyster, Jan Miense Molenaer, Bartholomeus van der Helst, Jan Steen, Jan de Bray, Jacob van Ruisdael, Gerrit Adriaenszoon Berckheyde.
