content: '''Margaery Tyrell''' is a fictional character in the ''A Song of Ice and Fire'' series of high fantasy novels by American author George R. R. Martin, and its television adaptation ''Game of Thrones''.
  Margaery is first mentioned in ''A Game of Thrones'' (1996) and first appears in ''A Clash of Kings'' (1998). She is a member of the House Tyrell, the second wealthiest and largest of the eight Great Houses in Westeros. She is twin sister to Loras Tyrell and the granddaughter of Olenna Tyrell. She subsequently appeared in ''A Storm of Swords'' (2000), ''A Feast for Crows'' (2005), and ''A Dance with Dragons'' (2011). Like her grandmother, she is shrewd, ambitious and adaptable, and uses her beauty, generosity and family influence to secure power for herself. Having wed herself to three different kings over the course of the narrative, she is one of the most influential political figures in Westeros, which often brings her into conflict with her chief rival at court, Cersei Lannister.
  Margaery is portrayed by English actress Natalie Dormer in the HBO television adaptation, a role for which she has received critical acclaim.  Margaery is one of the most popular supporting characters in both the books and television show, and is often cited as a prominent example of the story's strong feminist themes.
