Isognathus occidentalis is a moth of the family Sphingidae. It is known from Venezuela, northern Brazil and French Guiana.
It is similar to Isognathus excelsior but distinguishable by the pale brown underside of the abdomen. There are probably multiple generations per year.
The larvae have been recorded feeding on Himatanthus lancifolius. They have long tails and very colourful, suggesting they are unpalatable to birds.
