We analysed coexistence patterns between two mesocarnivores, Geoffroy's cat (Leopardus geoffroyi: Felidae) and culpeo fox (Pseudalopex culpaeus: Canidae), in northern Patagonia, Argentina. We examined spatial distribution influenced by land cover, anthropogenic disturbance and invasive hare presence, and analysed temporal activity patterns and dietary composition. If competitive exclusion accounts for carnivore coexistence in this system, we predicted segregation would occur in one or more of these aspects as a mechanism for coexistence. We performed camera trapping in Nahuel Huapi National Park, from February to May 2012 and January to April 2013. Using camera detections, we analysed spatial patterns with co‐occupancy modelling and temporal patterns by fitting kernel density estimates and measuring overlap. We performed a dietary meta‐analysis using available literature and performed a discriminant function analysis of diet categories between species. We observed high spatial and temporal overlap between Geoffroy's cats and culpeo foxes. We found no evidence of segregation in relation to land cover occupancy, anthropogenic disturbance, invasive hare occurrence or activity patterns. Though both species consumed predominantly small and medium mammals, Geoffroy's cats consumed more birds, reptiles and amphibians, and culpeo foxes consumed more large mammals, carrion and plant material; coexistence between these two carnivores in this Patagonian protected area appears to be facilitated by diet segregation.
