Daeron Targaryen may refer to:

  1. King Daeron I Targaryen, also known as "the Young Dragon". Eldest son of King Aegon III Targaryen and brother of King Baelor the Blessed. He briefly conquered Dorne but ultimately died without issue in his efforts to hold it. He was succeeded by his brother Baelor.
  2. King Daeron II Targaryen, also known as "Daeron the Good". Son of King Aegon IV Targaryen, who was himself the cousin of Daeron I, which makes Daeron II the first cousin once removed of Daeron I. He would ultimately succeed where his namesake failed and bring Dorne into fold through marriage rather than conquest.
  3. Prince Daeron Targaryen, the son of Aegon V and brother of Aerys II. Had his brother died without issue or being overthrown, he would have ascended the throne as "Daeron III".
