证券交易所（英语：Stock exchange）是买卖股票、公司债、公债等有价证券的市场。集合有价证券的买卖者，经过证券经纪人的居间完成交易。

最早的证券交易所是1602年设立的荷兰阿姆斯特丹交易所。在中国，最早的证券交易所是1905年外商组织的上海众业公所，以及1918年设立的北平证券交易所。现代交易所中规模较大的，如纽约和伦敦的证券交易所，都经营各个国家的证券交易。证券交易所的出现，为证券买卖创造了一个常设市场，成为货币资本借以实现长期投资的机构，因为通常称它为长期金融市场。

A stock exchange or bourse is an exchange where stock brokers and traders can buy and/or sell stocks (also called shares), bonds, and other securities. Stock exchanges may also provide facilities for issue and redemption of securities and other financial instruments, and capital events including the payment of income and dividends. Securities traded on a stock exchange include stock issued by listed companies, unit trusts, derivatives, pooled investment products and bonds. Stock exchanges often function as "continuous auction" markets, with buyers and sellers consummating transactions at a central location, such as the floor of the exchange.
