Cynarctoides is an extinct genus of the Borophaginae subfamily of canids native to North America. It lived from the Early Oligocene to the Middle Miocene, 33.3—13.6 Mya, existing for approximately {{Mya|33.3-13.6|million years}}. Seven species are currently recognised, all of which are estimated to have weighed no more than {{convert|1|kg}}. They had an unusual dentition that implies an omnivorous, or possibly even herbivorous, diet.{{cite book |last1= Wang |first1= Xiaoming | last2= Tedford | first2= Richard H. | date= 2008 |title= Dogs, Their Fossil Relatives and Evolutionary History |publisher= Columbia |page= 38 |isbn= 978-0-231-13528-3}}
