A queen mother is a former queen consort, often a queen dowager, who is the mother of the reigning monarch. The term's usage in English dates back to the early 1560s. It arose in hereditary monarchies in Europe and is also used to describe a number of similar yet distinct monarchical concepts in non-European cultures around the world.

" Queen Mother" usually, in English, refers to Queen Elizabeth the Queen Mother (queen consort, 1936–1952; queen mother, 1952–2002), who was the mother of Queen Elizabeth II and one of the few people to use the term as an official style. However, it was also used as an official title in Thailand where Sirikit, the mother of King Vajiralongkorn, was officially styled "The Queen Mother".

Status It is unclear if a queen consort whose husband abdicates the throne, or a queen regnant who abdicates, and is the mother of the current monarch would be the queen mother. In many countries, such as the United Kingdom, a monarch loses the title of king or queen after abdication. For example, Juliana of the Netherlands, who abdicated in favor of her daughter Beatrix, was sometimes colloquially referred to as the queen mother despite declining the title and having reverted to being a princess. Queen Paola of Belgium, whose husband Albert II abdicated but retained the title of king, has generally been referred to as the queen mother of Philippe despite not being a queen dowager.

A former queen consort who is the grandmother of the reigning monarch is sometimes called the queen grandmother. Queen Sri Savarindira of Thailand was known by this style.Finestone, Jeffrey.

United Kingdom

The title "queen mother" evolved to distinguish a queen dowager from all other queens when she is also the mother of the reigning sovereign. Thus, upon the death of her husband, King George V, Queen Mary became queen mother, retaining the status throughout the reigns of her sons, Edward VIII and George VI.

There is no male equivalent to a queen mother (i.e. "king father"). This would occur only if the husband of a queen regnant were to outlive the queen and was thereafter father to the new king or queen. Such a situation has never occurred. Since the title "queen mother" derives from the woman's previous title of "queen", it would also be incongruous to call such a father of a monarch the "king father", as the husbands of queens regnant are not given the title "king", but rather titled as a prince. The exact title such a person would assume has not been clarified by royal lineage experts. "Prince father" is a possibility.U.S. National Archives, "When Queen Elizabeth Dies", Prologue Magazine, Summer 1998

Ottoman Empire

In the Ottoman Empire, valide sultan () or sultana mother was the title held by the mother of a ruling Sultan. The title was first used in the 16th century for Hafsa Sultan, consort of Selim I and mother of Suleiman the Magnificent, superseding the previous title of mehd-i ülya ("cradle of the great"). The Turkish pronunciation of the word Valide is .

The second position the most important position in the Ottoman Empire after the sultan himself and being more powerful in the hierarchy than Haseki sultan. As the mother to the sultan, by Islamic tradition ("A mother's right is God's right"), the valide sultan would have a significant influence on the affairs of the empire. She had great power in the court and her own rooms (always adjacent to her son's) and state staff. In particular during the 17th century, in a period known as the "Sultanate of Women", a series of incompetent or child sultans raised the role of the valide sultan to new heights.Peirce, Leslie P., The Imperial Harem: Women and Sovereignty in the Ottoman Empire, Oxford University Press, 1993, (paperback)

India In India, a queen (usually styled rani, or in the Muslim tradition, begum) who becomes queen-mother was known in Sanskrit and Hindi as a rajamata - literally, mother of the king/monarch.

Africa

In Eswatini, the queen mother, or Ndlovukati, reigns alongside her son. She serves as a ceremonial figurehead, while her son serves as the administrative head of state. He has absolute power. She is important at festivals such as the annual reed dance ceremony.

In many matrilineal societies of West Africa, such as the Ashanti, the queen mother is the one through whom royal descent is reckoned and thus wields considerable power. One of the greatest leaders of Ashanti was Nana Yaa Asantewaa (1840–1921), who led her subjects against the British Empire during the War of the Golden Stool in 1900.

In more symbolically driven societies such as the kingdoms of the Yoruba peoples, the queen mother may not even be a blood relative of the reigning monarch. She could be a female individual of any age who is vested with the ritual essence of the departed queens in a ceremonial sense, and who is practically regarded as the monarch's mother as a result. A good example of this is Oloye Erelu Kuti I of Lagos, who has been seen as the iya oba or queen mother of every succeeding king of that realm, due to the activities of the three successors to her noble title that have reigned since her demise.
