%X This paper analyses the trophic relationships and the degree of overlap between the diet of Spanish ibex (Capra pyrenaica), red deer (Cervus elaphus), fallow deer (Dama dama) and mouflon (Ovis musimon) in the Cazorla, Segura and Las Villas National Park (Southeastern of Spain). Stomach content was used as the basis for diet evaluation. The most heavily consumed plant species by the four herbivores were Quercus rotundifolia, Phillyrea latifolia, Rosmarinus officinalis, Oryzopsis paradoxa and Festuca arundinacea. Spanish ibex and red deer were the ungulates with the most similar diet (53.7% overlap), both were browsers and consumed large amounts of woody matter. Fallow deer and mouflon had similar feeding habits, both are grazers and have a high intake of grasses. There were very low levels of overlap between the ibex and red deer diet with that of fallow deer and mouflon, respectively. Mouflon was the largest forbs consumer, fallow deer consumed most camephytes and red deer consumed most trees and shrubs. None of the four ungulates had absolutely definitive diets that could class them strictly as browsers or grazers, however certain trends suggested that ibex and red deer primarily behave as browsers while fallow deer and mouflon are grazers, although this was not a strict division. [fr] Nous avons ¨¦tudi¨¦ le degr¨¦ de superposition entre la di¨¨te du bouquetin (Capra pyrenaica, cerf (Cervus elaphus), daim (Dama dama) et mouflon (Ovis musimon) dans le Parc National de Cazorla, Segura et Las Villas (SE de l'Espagne). Pour l'¨¦valuation de la di¨¨te, nous nous sommes bas¨¦s sur les contenus stomachaux. Les esp¨¨ces les plus consomm¨¦es par les quatre herbivores ¨¦taient Quercus rotundifolia, Phillyrea latifolia, Rosmarinus officinalis, Oryzopsis paradoxa et Festuca arundinacea. Le bouquetin et le cerf montraient la di¨¨te la plus semblable (53,77o de superposition) puisque tous deux broutaient une grande quantit¨¦ de mati¨¨re ligneuse. Le mouflon et le daim montraient des habitudes similaires au niveau de l'alimentation, mangeant des herbes et consommant une grande quantit¨¦ de gramin¨¦es. Les di¨¨tes du bouquetin et du cerf ne se superposaient que tr¨¨s peu avec celles, respectivement, du daim et mouflon. Le mouflon consommait beaucoup de m¨¦gaphorbes tandis que le daim consommait surtout des chamaephytes et le cerf principalement arbres et arbrisseaux. Aucun des quatre ongul¨¦s ¨¦tudi¨¦s montrait des di¨¨tes tr¨¨s strictes (broutage ou consommateur de gramin¨¦es); cependant, on peut signaler que le bouquetin et le cerf pr¨¦sentaient plus des caract¨¨res de brouteurs tandis que le
