Mace Tyrell is a character from the fantasy series A Song of Ice and Fire by George R.R. Martin and its television adaptation, Game of Thrones. He is the head of House Tyrell, one of the wealthiest and most powerful families in the Seven Kingdoms. Mace is known for his large stature, jovial personality, and lack of political acumen, often relying on his mother, Olenna Tyrell, for guidance. As the Lord of Highgarden, Mace Tyrell plays a significant role in the political landscape of Westeros. He is the father of Margaery Tyrell and Loras Tyrell, both of whom are central figures in the series. Mace's ambition is to elevate his family's status through strategic marriages and alliances, particularly with the Lannisters.
