Daeron Targaryen is an unseen character in Game of Thrones. He is long dead by the time the series begins.

Background
Daeron was the youngest son of King Aegon V Targaryen. He was betrothed to Olenna Redwyne, but she took a great dislike to his "twitchy little ferret's face and ludicrous silver hair", and their engagement ended when Olenna seduced her sister Viola's intended husband Luthor Tyrell.

Season 4
After the Purple Wedding, Olenna recounted the story of how she escaped her engagement to Daeron to her granddaughter Margaery Tyrell, as a lesson on how to manipulate her future husband Tommen Baratheon.

In the books
In the A Song of Ice and Fire novels, Olenna Tyrell tells Sansa Stark a tale of how she had once been betrothed to a Targaryen Prince. Olenna claims that it was her who had not wanted the marriage, and that it and been her who had "put an end to it".

In The World of Ice and Fire, this Prince is revealed to be Daeron Targaryen, the youngest son and fourth born child of King Aegon V Targaryen and his wife Queen Betha Blackwood.

Daeron and Olenna were betrothed in 237 AC, having arranged by Daerons mother. They were both nine years old at the time, significantly younger that in the television series. After his three older siblings, Duncan, Jaehaerys and Shaera had broken their own betrothals - Duncan to marry Jenny of Oldstones, Jaehaerys and Shaera to marry each other - Daeron broke his betrothal to Olenna as well. He did so when he was eighteen years old, in 246 AC. But while his brothers had broken their betrothals for another woman, this was not the case for Daeron. He preferred the companionship of Ser Jeremy Norridge, a young knight whom he had befriended when they were squires together at Highgarden.

In 251 AC, Prince Daeron led an army against the Rat, the Hawk and the Pig; three individuals who had assaulted Princess Aelora Targaryen at a masked ball in 217 AC, which contributed to her suicide soon afterward. Though they managed to quash the rebellion, Daeron was killed in battle, as was Ser Jeremy, who died by his side.

Behind the scenes
Due to the simplification of the Targaryen lineage by removing Jaehaerys II from the line of kings and making Aerys and Rhaella the children of Aegon V rather than his grandchildren, Dareon is Aerys and Rhaella's brother in the TV series though he was their uncle in the books.
