Electoral fraud, sometimes referred to as election manipulation, voter fraud, or vote rigging, involves illegal interference with the process of an election, either by increasing the vote share of a favored candidate, depressing the vote share of rival candidates, or both. It differs from but often goes hand-in-hand with voter suppression. What exactly constitutes electoral fraud varies from country to country, though the goal is often election subversion.

An electoral roll is a compilation that lists persons who are entitled to vote for particular elections in a particular jurisdiction. The list is usually broken down by electoral districts, and is primarily prepared to assist election officials at polling places. Most jurisdictions maintain permanent electoral rolls, which are updated continuously or periodically, while some jurisdictions compile new electoral rolls before each election. Electoral rolls are the result of a process of voter registration. In most jurisdictions, voter registration is a prerequisite for voting at an election. Some jurisdictions do not require voter registration, and do not use electoral rolls, such as the state of North Dakota in the United States. In those jurisdictions a voter must provide identification and proof of entitlement to vote before being permitted to vote.
