Autodesk Arnold (also known as simply Arnold) is a computer program for rendering three-dimensional, computer-generated scenes using unbiased, physically-based, Monte Carlo path tracing techniques. Created in Spain by Marcos Fajardo, it was later co-developed by his company Solid Angle SL (now owned by Autodesk) and Sony Pictures Imageworks.

Arnold is one of the most widely used photorealistic rendering systems in computer graphics worldwide, particularly in animation and VFX for film and television.
