卡通渲染（英语：Cel-shading或者Toon Shading）是一种去真实感的渲染方法，旨在使电脑生成的图像呈现出手绘般的效果。为了使图像可以与漫画或者卡通达到形似的效果，专业人员通常使用卡通渲染着色器进行处理。卡通渲染是在大约21世纪初期，作为计算机图形学的副产物出现的新技术，并且主要应用于电子游戏中；然而，它可以呈现出如手绘动画一样简洁明了的效果。

在其英语名Cel-shading中，Cel一词来自常用于传统动画的材料赛璐珞。

Cel shading (often misspelled as "cell shading") or toon shading is a type of non-photorealistic rendering designed to make 3-D computer graphics appear to be flat by using less shading color instead of a shade gradient or tints and shades. Cel-shading is often used to mimic the style of a comic book or cartoon and/or give it a characteristic paper-like texture. There are similar techniques that can make an image look like a sketch, an oil painting or an ink painting. It is somewhat recent, appearing from around the beginning of the twenty-first century. The name comes from cels (short for celluloid), the clear sheets of acetate, which are painted on for use in traditional 2D animation.
