National Galleries of Scotland () is the executive non-departmental public body that controls the three national galleries of Scotland and two partner galleries, forming one of the National Collections of Scotland. The purpose of the National Galleries of Scotland (NGS) was set out by an Act of Parliament in the National Galleries of Scotland Act 1906, amended by the National Heritage (Scotland) Act 1985. Its role is to manage the National Galleries of Scotland, care for, preserve and add to the objects in its collections, exhibit artworks to the public and to promote education and public enjoyment and understanding of the Fine Arts. It is governed by a Board of Trustees who are appointed by ministers of the Scottish Government.

Since then, the Royal Institution building became known as the Royal Scottish Academy. In 1959, National Galleries of Scotland expanded further with the establishment of the Scottish National Gallery of Modern Art (SNGMA), housed in Inverleith House in the Royal Botanic Garden Edinburgh. Twentieth-century artworks in the National Galleries collection were relocated to the new gallery, and the gallery began to acquire many more objects after 1960. By 1984, the modern art gallery had outgrown its first home, and the SNGMA relocated to the vacant John Watson's Institution building, a former school. In 1999, the SNGMA expanded with the opening of The Dean Gallery (now called Modern Two) in a former orphanage opposite the Gallery of Modern Art.
