Counter-Admiral Michael Johannes Petronius Bille (8 November 1769 – 27 March 1845) was a Danish naval officer.
Born in Stege on the island of Møn into a naval family, he served in the French Revolutionary and Napoleonic Wars.
After days of struggle, the ship ran aground off Newport, County Mayo, Ireland on 17 March 1782.
Bille became an officer in the Danish-Norwegian Navy in 1789 and participated in the Battle of Copenhagen on 2 April 1801, where he commanded the lower battery of the Prøvesteenen which fired the first shot at the British.
After three years he moved the school into a building that lay outside Danzig at the mouth of the Radaune River because the St. Jacob Church was inadequate.
