A prefect badge is given to fifth year students who are chosen to represent their house as prefects. There are two students in each Hogwarts house, a boy and a girl. The prefect badge has a large 'P' across a background of the house's colours, as well as the house symbol (such as a lion for Gryffindor).[1][2]


Over Christmas of 1992, Fred and George Weasley magically altered Percy's prefect badge to read "Pinhead" instead. He failed to notice this at the Christmas feast that year, causing bewilderment on his part as to what those around him were amused at.[3]

During the 1993-1994 school year, a Gryffindor prefect lost their badge, and posted a note looking for its return on the Gryffindor pasteboard. Harry Potter, Ronald Weasley, and Hermione Granger located the badge in the Entrance Hall, near the Hufflepuff hourglass, and were awarded ten house points for returning it.[4]

Behind the scenes

  • The description of how a Prefect badge looks has changed throughout the series. In early editions of Harry Potter and the Philosopher's Stone, Percy's Prefect badge is described as a "shiny silver". However, Ron's Prefect badge in Harry Potter and the Order of the Phoenix is red and gold, implying that the Prefect badges are coloured by house. Later printings of Philosopher's Stone change the description of Percy's badge to match Ron's. Oddly, the Prefect badge seen on Pottermore returns to the original silver design.
