票站调查(英文:Exit Poll)，又常被称做「出口民调」，是指在选举进行期间，设于票站出口，访问刚投票的人的投票意向的民意调查。其主要目的是为了分析及解读选民的投票行为，并即时知道选举形势。所以，很多国家和地区的学者也会与学术组织合作进行票站调查，并分析有关数据。一般而言，票站调查的结果要在选举结束后才可公布，以免影响选民投票意向。而票站调查的结果亦可作为在官方点票结果公布前对选举结果的估计。不过票站调查也可以用作配票工具而被杯葛。

An election exit poll is a poll of voters taken immediately after they have exited the polling stations. Unlike an opinion poll, which asks for whom the voter plans to vote, or some similar formulation, an exit poll asks for whom the voter actually voted. A similar poll conducted before actual voters have voted is called an entrance poll. Pollsters – usually private companies working for newspapers or broadcasters – conduct exit polls to gain an early indication as to how an election has turned out, as in many elections the actual result may take hours or even days to count.
