What is Ron Weasley's middle name?

The story behind the answer

Ron’s full name is Ronald Bilius Weasley—Bilius being his middle name. It comes from his late Uncle Bilius, whom Ron mentions in Prisoner of Azkaban as the relative who saw a Grim and died 24 hours later, a favorite Weasley family anecdote. J.K. Rowling often uses family names for middle names, reflecting wizarding tradition (e.g., Ginevra Molly Weasley, Harry James Potter).

Memory tip: Bilius sounds like “bilious,” meaning sickly or nauseated. Picture Ron turning green (bilious!) whenever spiders are around—his well-known fear—while reminding yourself he’s named after Uncle Bilius. That vivid link helps lock in “Bilius” as his middle name.
