Olenna

Olenna is a feminine given name and a proper noun used in various contexts. The most prominent reference is Olenna Tyrell, a fictional character in George R. R. Martin's A Song of Ice and Fire novels and the HBO television adaptation Game of Thrones. Known as the Queen of Thorns, she is the matriarch of House Tyrell, ruling the Reach and a key political player who wields influence through wit, negotiation, and alliances. In the books, she is the grandmother of Margaery Tyrell and Loras Tyrell, and she plays a pivotal role in the dynastic intrigues surrounding the Iron Throne. The character is portrayed by Diana Rigg in the television adaptation.

Beyond fiction, Olenna is not widely documented as a real-world personal name, place, or organization in major reference works. When encountered in non-fiction contexts, it is often a misspelling or variation of other names, or used in fan fiction and fan media related to the character.
