Sharpe's Waterloo
 is a historical novel in the Richard Sharpe series by Bernard Cornwell. Originally published in 1990 under the title Waterloo, it is the eleventh and final novel of the "original" Sharpe series (beginning with Sharpe's Eagle), and the twentieth novel in chronological order.


Napoleon having escaped from Elba, Richard Sharpe leaves his farm in Normandy to rejoin the British Army, and is created a Lieutenant Colonel of a Dutch-Belgian cavalry regiment, a sinecure to give him standing as one of the Prince of Orange's staff officers. Sharpe's lover Lucille has followed him to Belgium with their infant son, Henri-Patrick, as has Sharpe's friend Patrick Harper, now a civilian who has ostensibly come to Belgium to trade in horses, but unofficially to resume his place at Sharpe's side.
