The list of late medieval works on the Crusades provides those contemporaneous written accounts and other artifacts of the Crusades covering Crusades against Christians, the Baltic Crusades, which lasted until 1560, and the later Crusades in the Levant from the fall of Acre in 1291 through the Crusade of King Sebastian in 1578. The scope of these expeditions is provided in List of Crusades. These sources include chronicles, criticisms, personal accounts and official documents. Some of these works cover timeframes that overlap the other articles in the series Historians and histories of the Crusades. As such, these lists support the medieval historiography of the Crusades.

These include Recueil des historiens des croisades (RHC), Monumenta Germaniae Historica (MGH), Revue de l'Orient Latin/Archives de l’Orient Latin (ROL/AOL) and the Rolls Series.

Thirteenth century The first of the Crusades against Christians was the Albigensian Crusade of 1209–1229, begun under Philip II of France and continued with Louis IX of France. After the fall of Acre in 1291, there was a significant push for a new Crusade to retake the Holy Land. Histories written after that time have typically combined a chronology with proposals for additional Crusades. This period also saw the rise of knighthood and the notion of chivalry.
