美国otc市场指美国场外交易的一种模式。
美国场外柜台交易系统（Over the Counter Bulletin Board，OTCBB）又称布告栏市场，是由NASDAQ的管理者全美证券商协会（NASD）所管理的一个交易中介系统。
为了便于交易并加强OTC市场的透明度，NASD于1990年开通了OTCBB电子报价系统，将一部分粉红单市场的优质股票转到OTCBB上来。OTCBB电子报价系统提供实时的股票交易价和交易量。在粉红单市场流通的股票多于在OTCBB上流通的股票。
在OTCBB上面流通交易的股票，都是不能达到在那斯达克全国市场（National Market）或小资本市场（Small Capital）上挂牌上市要求的公司的股票，因此有人说它属于“未上市证券市场”。
