The McGregor Museum in Kimberley, South Africa, originally known as the Alexander McGregor Memorial Museum, is a multidisciplinary museum which serves Kimberley and the Northern Cape, established in 1907.

Housed at first in a purpose-built museum building in Chapel Street, Kimberley, and spreading to occupy further spaces in the city, the museum was, and still is, governed by a Board of Trustees, aided financially by the Kimberley municipality (up to the 1950s), then by the Cape Provincial Administration and, today, by the Northern Cape Administration through the Department of Sport, Arts and Culture. In May 2014 it was declared a Provincial Public Entity, effective from 1 April 2014.^[1]

Alexander McGregor had been a Mayor of Kimberley, whose wife bequeathed the building to perpetuate his memory.^[2]

Today the museum has its headquarters at the old Kimberley Sanatorium building in Belgravia, Kimberley, and it has several satellites including the original building in Chapel Street.^[2] The museum was founded on 24 September 1907. By coincidence 24 September was chosen as Heritage Day, a public holiday in South Africa post-1994.

The McGregor Museum is a primary research institute in and for the Northern Cape (and is anticipated to have a role in articulation with the School of Heritage which is to be a part of the Sol Plaatje University^[3]) in fields of natural and cultural history (including zoology, botany, general history, South African struggle history, archaeology, social anthropology). It curates important collections and archival material (see below) and, on the basis of its collections and research activities, performs educational and outreach functions to the community locally and throughout the province. Research programs include international collaborative projects.

The McGregor Museum operates as a Provincial Public Entity (as of April 2014), governed by a board of trustees. It was originally aided by the Kimberley Municipality, De Beers and many donors (from 1907); then by the Cape Provincial Administration (from 1958); and, from 1994, as a Province-aided Museum receiving an annual grant from the Department of Sport, Arts and Culture, Northern Cape Province, which also employed the staff of the museum.

Directors of the McGregor Museum have been:

• Maria Wilman (1908–1946)
• John Hyacinth Power (1947–1958)
• Rudolph Carl Bigalke (1958–1964)
• Richard Liversidge (1966–1986)
• Elizabeth Anne Voigt (1987–1999)
• Colin Fortune (2000–2014)
• Sunet Swanepoel (2014–2017 Acting), (2017– )

The museum houses major natural history and cultural history collections including a botanical herbarium, zoology collections, a history archive (including documents, photographs and oral history recordings), ethnography collections, archaeology and rock art collections, physical anthropology, palaeontology and geology collections. Most of these fields are represented by professional staff and collection managers, and the collections and associated research programs are reflected in permanent and temporary exhibits in various sections and buildings of the museum as well as in outreach programs in the province and displays in smaller museums.

Outgrowing available space at its buildings in town, the museum's headquarters were moved in 1973 to the former Kimberley Sanatorium (built in 1897), which at one time served also as the Hotel Belgrave (1908–1933) and as the Holy Family Convent School, Kimberley (1933–1971). The new museum headquarters were officially opened on 22 November 1976. For the duration of the Siege of Kimberley (14 October 1899 – 15 February 1900) during the Anglo-Boer War, Cecil John Rhodes lodged in rooms at what was then the Sanatorium.

Branches of the McGregor Museum today include the original McGregor Memorial Museum in town (city history displays), the Duggan-Cronin Gallery (photographic and ethnographic museum), two house museums, Dunluce and Rudd House, the Pioneers of Aviation Museum, the Magersfontein Battlefield Museum, Wonderwerk Cave near Kuruman and the Wildebeest Kuil Rock Art Centre outside Kimberley.
