William, Lord Hastings (died 1483) was a close friend and chamberlain of King Edward IV. He controlled access to that king, leading to charges that he aided the lusty Edward in his debauches. Hastings was commander of a wing of the Yorkist army at the battles of Bosworth
, with much less success than the other commanders, King Edward and Richard Duke of Gloucester. After Edward IV died in 1483, it was Hastings who hurriedly summoned Gloucester to take charge of the government as Lord Protector. But Richard eventually found Hastings an impediment and had him executed. Not long after, Richard took the throne.
