The Battle of Holmedon Hill or Battle of Homildon Hill was a conflict between English and Scottish armies on 14 September 1402 in Northumberland, England. The battle was recounted in Shakespeare's Henry IV, part 1. Although Humbleton Hill is the modern name of the site, over the centuries it has been variously named Homildon, Hameldun, Holmedon, and Homilheugh.

Henry IV, Part 1 is a history play by William Shakespeare, believed to have been written not later than 1597. The play dramatises part of the reign of King Henry IV of England, beginning with the battle at Homildon Hill late in 1402, and ending with King Henry's victory in the Battle of Shrewsbury in mid-1403. In parallel to the political conflict between King Henry and a rebellious faction of nobles, the play depicts the escapades of King Henry's son, Prince Hal, and his eventual return to court and favour.
