Maud of Wales (Maud Charlotte Mary Victoria; 26 November 1869 – 20 November 1938) was Queen of Norway as the wife of King Haakon VII. The youngest daughter of King Edward VII and Queen Alexandra of the United Kingdom and a sister of George V, she was known as Princess Maud of Wales before her marriage, as her father was the Prince of Wales at the time.

A daughter of Edward VII of the United Kingdom and Alexandra of Denmark, Maud was the youngest of six children. She grew up in a warm and informal environment under the supervision of her mother, contrasting with the stricter upbringing of her older siblings. From an early age, Maud showed a spirited and lively nature, enjoying outdoor pursuits and sports; she was among the first British princesses to ride a bicycle and often spent time in the gardens and grounds of Sandringham House. Her education, was primarily conducted at home, under the supervision of private tutors.

In 1896, Maud married her first cousin Prince Carl of Denmark. Following the dissolution of the union with Sweden in November 1905, Prince Carl was elected king of Norway as Haakon VII of Norway, and Maud became the first queen consort of an independent Norway in more than five centuries. Stepping into her new role, she combined her British upbringing with her Norwegian duties: while keeping strong ties to Britain, Maud embraced Norwegian national life, supported charitable causes particularly those connected to children, women, and the arts and took part in outdoor pursuits such as skiing.

Despite her reserved public demeanour, Maud played a steady and stabilising role in the early 20th-century Norwegian monarchy, acting as a bridge between British and Norwegian royal traditions. She was widely admired for her dignity, charitable work, and quiet influence at court. Maud died in London on 20 November 1938, six days before her 69th birthday.

Maud was born on 26 November 1869 at Marlborough House, London. She was the third daughter and fifth child of Albert Edward, Prince of Wales, and Alexandra, Princess of Wales. Albert Edward was the eldest son of Queen Victoria, and Alexandra was the eldest daughter of Christian IX of Denmark. Maud was christened "Maud Charlotte Mary Victoria" at Marlborough House by John Jackson, Bishop of London, on 24 December 1869. Her godparents were her paternal uncle Prince Leopold, for whom the Duke of Cambridge stood proxy; Prince Frederick William of Hesse-Kassel, for whom Prince Francis of Teck stood proxy; Count Gleichen; the Duchess of Nassau, for whom Princess Francis of Teck stood proxy; Charles XV of Sweden, for whom Swedish minister Baron Hochschild stood proxy; Princess Marie of Leiningen, for whom Princess Claudine of Teck stood proxy; her maternal aunt the Tsarevna of Russia for whom Baroness de Brunnow stood proxy; Crown Princess Louise of Denmark, for whom Madame de Bülow, wife of the Danish minister, stood proxy; and her great-great-aunt the Duchess of Inverness.

Growing up, Maud had a love for all outdoor sports. She was described as having a 'kind and cheerful disposition.' Of the three Wales girls, she was the most attractive. 'She did look so pretty and fresh,' wrote the Empress Frederick of Maud in 1895, 'like a little rose, with her bright eyes and dear intelligent expression.'

The tomboyish Maud was known as "Harry" to the royal family, after Edward VII's friend Admiral Henry Keppel, whose conduct in the Crimean War was considered particularly courageous at the time. Maud took part in almost all the annual visits to the Princess of Wales's family gatherings in Denmark and later accompanied her mother and sisters on cruises to Norway and the Mediterranean. She was a bridesmaid at the 1885 wedding of her paternal aunt Beatrice to Prince Henry of Battenberg, and at the wedding of her brother George to Mary of Teck in 1893.

Maud, along with her sisters, Victoria and Louise, received the Imperial Order of the Crown of India from their grandmother Queen Victoria on 6 August 1887. Like her sisters, she also held the Royal Order of Victoria and Albert (First Class) and was a Dame Grand Cross of the Order of the Hospital of St. John of Jerusalem.
