场外电子交易板（英语：Over-The-Counter Bulletin Board或OTCBB）是美国一个以电子方式交易的股票系统，会显示实时报价，最后的出售价格和数量等数据，许多在此板交易的股票并没有在纳斯达克股票市场或任何一个国家的证券交易市场上市。

虽然该类证券交易由美国金融业监管局监督，但并不算是纳斯达克股票交易市场的一部分。美国证券交易委员会曾表示，骗徒经常声称OTCBB上市相当于纳斯达克上市，令投资者高估OTCBB上市的公司的规模。

The OTC (Over-The-Counter) Bulletin Board or OTCBB is a United States quotation medium operated by the Financial Industry Regulatory Authority (FINRA) for its subscribing members. It is used for many over-the-counter (OTC) equity securities that are not listed on the NASDAQ or a national stock exchange. Broker-dealers who subscribe to the system, which is not electronic, can use the OTCBB to enter orders for OTC securities that qualify to be quoted. According to the U.S. Securities and Exchange Commission (SEC), "fraudsters often claim or imply that an OTCBB company is a Nasdaq company to mislead investors into thinking that the company is bigger than it is".
