Preston Greenfield is a background character in Game of Thrones. He is played by an unidentified extra and first mentioned by name in "Two Swords". Ser Preston is a knight and a member of the Kingsguard, defending King Joffrey Baratheon as he defended King Robert Baratheon before him.
After Jaime returns to King's Landing, he goes over with Ser Meryn the placement of the Kingsguard members in defensive positions during Joffrey's wedding, and mentions Ser Preston.

In the books
In the A Song of Ice and Fire novels, Greenfield is a member of Robert Baratheon's Kingsguard. He is noted as the shortest member of the Kingsguard. He accompanied Robert on his boar hunting trip where he was mortally wounded. He pledges allegiance to Joffrey following Robert's death.
Ser Preston is killed in the Riot of King's Landing and replaced by Ser Balon Swann, who has been mentioned in the series but not as part of the Kingsguard. In the series no Kingsguard is shown to be killed by the rioters.
Ser Preston is later mentioned as being alive at the time of Joffrey's wedding, so apparently he simply wasn't killed in the riots in the TV continuity.
