道氏理论（Dow Theory）是一个关于美国股票市场创造财富方式的活动方式理论。

理论起初来源于新闻记者、首位华尔街日报（Wall Street Journal）的记者和道琼斯公司（Dow Jones and Company）的共同创立者查尔斯·亨利·道（Charles Henry Dow，1851年—1902年）的社论。在其去世后，由威廉·彼得·汉密尔顿（William Peter Hamilton）、罗伯特·雷亚（Robert Rhea）和E·乔治·希弗（E.George Schaefer）总结出来并予以命名。道氏他本身从未使用过“道氏理论”这个词。

The Dow theory on stock price movement is a form of technical analysis that includes some aspects of sector rotation. The theory was derived from 255 Wall Street Journal editorials written by Charles H. Dow (1851–1902), journalist, founder and first editor of The Wall Street Journal and co-founder of Dow Jones and Company. Following Dow's death, William Peter Hamilton, Robert Rhea and E. George Schaefer organized and collectively represented Dow theory, based on Dow's editorials. Dow himself never used the term Dow theory nor presented it as a trading system.
