选票系选举时候表达意见的文档，选民用选票来表达选择哪个候选人，或者在公民投票中，表达自己赞成或反对议案，投票权就表示选民能有这张选票来表答意见。

选票上面，会顺串行出所有候选人姓名、政党等信息，并有圈选字段让选民选择，选民按选举法规用盖印、笔画、戳洞等方式，选出自己想要投的候选人，再放入票箱就完成投票。之后，选举机关会开箱点算选票，或者公开唱票。

污损或携走选票是违法的行为，通常会被选举机关处罚。

选票通常是用纸张制作，由于科技的演进，已经有电子选票的产生。

A ballot is a device used to cast votes in an election, and may be a piece of paper or a small ball used in secret voting. It was originally a small ball (see blackballing) used to record decisions made by voters.

Each voter uses one ballot, and ballots are not shared. In the simplest elections, a ballot may be a simple scrap of paper on which each voter writes in the name of a candidate, but governmental elections use pre-printed to protect the secrecy of the votes. The voter casts his/her ballot in a box at a polling station.
