The MacRobert Baronetcy, of Douneside in the County of Aberdeen, was a title in the Baronetage of the United Kingdom. It was created on 5 April 1922 for Alexander MacRobert, a self-made millionaire. He was succeeded by his eldest son Alasdair in June of that year. Tragedy struck the family again when Alasdair was killed in a flying accident in 1938, and the title passed to his younger brother Roderic. In May 1941 Roderic was killed in action whilst flying a Hawker Hurricane fighter in the Middle East, and just over a month later on 30 June 1941, the title became extinct when the youngest brother Iain, was also killed in action whilst serving with the Royal Air Force. Their mother, Rachel, Lady MacRobert (1884–1954), gave £25,000 to purchase a Short Stirling bomber, the aircraft was named MacRobert's Reply in memory of her three sons. Lady MacRobert believed that her sons had lived up to the family motto Virtutis Gloria Merces – translated as Honour is the Reward of Bravery. The MacRobert Award, which has been presented every year since 1969 by the Royal Academy of Engineering, is named in honour of Lady MacRobert.

Sir Alexander MacRobert, 1st Baronet was a self-made millionaire from Aberdeen, Scotland. He came from a working-class background and left school when he was twelve to start his working life sweeping floors in Stoneywood Paper Mill; his education was continued by attending evening classes and he gained several qualifications as his early career progressed. At the beginning of 1884 MacRobert travelled to India to take up employment in a woollen mill in Cawnpore, or Kanpur as it is now known. By 1920 he had built up a portfolio of companies enabling him to found the British India Corporation. He was raised to a baronet at the beginning of 1922, choosing to be named Sir Alexander MacRobert of Cawnpore and Cromar of the County of Aberdeen.
