Ovine rinderpest, also commonly known as peste des petits ruminants (PPR), is a contagious disease primarily affecting goats and sheep in Central and Southern Africa, the Middle East, the Indian subcontinent, and, since June 2008, Morocco. The cases in Morocco indicate a crossing of the natural barrier of the Sahara. It is caused by a species of the Morbillivirus genus of viruses. The disease is highly contagious, and has roughly an 80 percent mortality rate in acute cases.

In 2017, it was reported that the disease was affecting saiga in Mongolia, causing near-catastrophic herd depletion for the endangered species.

Traditionally, the name kata was given to stomatitis and pneumoenteritis of the Nigerian dwarf goat. Peste des Petits Ruminants was the French name of a similar disease of sheep and goats first described in Côte d'Ivoire (Ivory Coast) in 1942. These diseases have been shown to be very close to each other. 

Many authors prefer the name "Ovine Rinderpest". But official agencies such as the FAO and OIE use the French name "Peste des Petits Ruminants", "Peste Des Petits Ruminants", "Peste-des-Petits-Ruminants" or "Peste-des-petits-ruminants", even in English, although the phrase Goat Plague is becoming more widely used in the popular press. The French acronym, PPR, is commonly used among veterinary professionals in East Africa.

They are similar to those of rinderpest in cattle and involves oral necrosis, mucopurulent nasal and ocular discharges and diarrhoea though they vary according to the previous immune status of the sheep (enzootic or newly infected country). They also vary according to the breed of sheep. However fever in addition to either diarrhoea or signs of oral discomfort is sufficient for the diagnosis.
