Dogs Playing Poker is a series of oil paintings by C. M. Coolidge. All the paintings in the series feature anthropomorphized dogs in behaviors of playing poker, smoking cigars, dancing, playing baseball, and testifying in court. Of the 16 paintings, the nine in which dogs are seated around a card table playing poker and smoking cigars have become popular. The series has an appeal that has made it part of American pop culture.
