A page boy is a young male attendant at a wedding or cotillion. This type of wedding attendant is less common than it used to be, but is still a way of including young relatives or the children of relatives and friends in a wedding. A page is often seen at British royal weddings. There may be many pages for effect at cotillions.

Traditionally, page boys carry the bride's train, especially if she is wearing a dress with a long train. Because of the difficulty of managing the train, page boys are generally no younger than age seven, with older boys being preferred for more complicated duties.
