A voting machine is a machine used to record votes without paper. The first voting machines were mechanical but it is increasingly more common to use electronic voting machines. Traditionally, a voting machine has been defined by its mechanism, and whether the system tallies votes at each voting location, or centrally. Voting machines should not be confused with tabulating machines, which counts votes done by paper ballot.

Voting machines differ in usability, security, cost, speed, accuracy, and ability of the public to oversee elections. Machines may be more or less accessible to voters with different disabilities.

Tallies are simplest in parliamentary systems where just one choice is on the ballot, and these are often tallied manually. In other political systems where many choices are on the same ballot, tallies are often done by machines to give quick results.
