Count Emmo, Immo or Emmon is one of the first known counts of Loon in the region of modern Belgian Limburg. Before him one more count is known with confidence, Count Giselbert, but it is not certain that Giselbert was Emmo's father. Verhelst for example has proposed that he was his uncle, and that Giselbert's brother Count Arnulf was father of Emmo and also a count of Loon.
