Mauritshuis is a museum located in The Hague, Netherlands. It houses a collection of Dutch and Flemish art from the 15th to the 17th century, including some of the most famous paintings of the Dutch Golden Age. The museum is named after Johan Maurits, Count of Nassau-Siegen, who owned the building in the 17th century.

The collection includes works by famous Dutch artists such as Johannes Vermeer, Rembrandt van Rijn, Frans Hals, and Jan Steen. Among the highlights are Vermeer's "Girl with a Pearl Earring", "The Anatomy Lesson of Dr. Nicolaes Tulp" by Rembrandt, and "The Goldfinch" by Carel Fabritius.

The museum itself is housed in a 17th-century palace that was originally built as a home for John Maurice of Nassau, who was the governor of the Dutch colony in Brazil. The building was later used as a government office and then a museum in the early 19th century. It underwent extensive renovation and expansion in the early 21st century to modernize the facilities and improve the exhibition spaces.

Today, the Mauritshuis is one of the most popular museums in the Netherlands, attracting visitors from all over the world who come to see its outstanding collection of Dutch and Flemish art.
