Lydia Bennet is the youngest Bennet sister in The Lizzie Bennet Diaries, a 2012 modern web series adaptation of Pride and Prejudice, played by Mary Kate Wiles. She attends community college and studies costume theatre, and she starts out as the loud, flirtatious party girl of the family. Her vlogs are single continuous takes shot in varied locations, which gives them an unpolished, spontaneous feel.

She is best known for her spin-off vlog series, The Lydia Bennet, and for an arc in which George Wickham exploits her insecurities about being untalented and overlooked. Her drive comes from wanting to be taken seriously by her sisters, and she can hold a grudge for a long time, much like Lizzie. Over the story she moves from carefree bravado toward owning her mistakes.

The people who end up texting her are usually fans who enjoy a bold, funny sister with a big heart, along with anyone who has felt dismissed by the people closest to them. She stays in touch with cousin Mary and keeps everyone updated on family news, so she suits anyone who likes gossip with a conscience.
