笔迹分析 (Graphoanalysis) 指透过书写人的笔迹，分析其行为及性格，或者核对笔迹之真伪。笔迹分析工作一般由笔迹专家进行。

笔迹可以显示出性格、智力水平、思维及逻辑的具体反映。人书写的内容，能够反映其显意识；人书写的方法，能够反映其潜意识。笔迹分析可以从写者的书写风格，透析其的内心世界、个性特质、心理状态及情绪等。

Graphoanalysis is a form of the pseudoscience graphology in which an analysis of strokes in handwriting of any language or note taking system, and its deviation from "textbook standard", claim to make predictions of psychological traits. It was created by Milton N Bunker who first studied handwriting analysis around 1913. He formed the American Grapho Analysis Society by 1929, and in 1949 he incorporated the International Grapho Analysis Society (now the International Graphoanalysis Society or IGAS). Since 1961, IGAS has been the sole owner of all material, and intellectual property rights relating to graphoanalysis.
