The Actes and Deidis of the Illustre and Vallyeant Campioun Schir William Wallace, also known as The Wallace, is a long "romantic biographical" poem by the fifteenth-century Scottish makar of the name Blind Harry, probably at some time in the decade before 1488. As the title suggests, it commemorates and eulogises the life and actions of the Scottish freedom fighter William Wallace who lived a century and a half earlier. The poem is historically inaccurate, and mentions several events that never happened. For several hundred years following its publication, The Wallace was the second most popular book in Scotland after the Bible.

Sir William Wallace was a Scottish knight who became one of the main leaders during the First War of Scottish Independence.
