Ultimately from German München or Münichen (the earliest attested form, common in the late Middle Ages), probably via French Munich, like many other city names (Cologne, etc). First attested in the early 1600s; compare the slightly earlier English form Miniken (whence minikin) which is attested prior to 1566 and derives directly from the German name.
