Adolf Ludvig Gustav Fredrik Albert Badin né Couchi, known as Badin (1747 or 1750 – 1822) was a Swedish court servant (Kammermohr) and diarist. Originally a slave, he was the foster son and servant of Queen Louisa Ulrika of Sweden and a servant to his foster sister Princess Sophia Albertine of Sweden. His original name was Couchi, but he was commonly known as Badin ('mischief-maker' or 'trickster'). After the death of Queen Lovisa Ulrika, Badin was given three farmhouses outside Stockholm by the Swedish king, which gave him an income and some financial security. He was also given several honorary titles such as chamberlain, court secretary, ballet master and Assessor (a judge's or magistrate's assistant)
