Girl Reading a Letter at an Open Window is an oil painting by Dutch Golden Age painter Johannes Vermeer. Completed in approximately 1657–59, the painting is on display at the Gemäldegalerie in Dresden. For many years, the attribution of the painting—which features a young Dutch woman reading a letter before an open window—was lost, with first Rembrandt and then Pieter de Hooch being credited for the work before it was properly identified in 1880. After World War II, the painting was briefly in possession of the Soviet Union. Apparently well-preserved, the painting may have been altered after the painter's death.
