List of polling organizations

This is a list of notable polling organizations by country. All the major television networks, alone or in conjunction with the largest newspapers or magazines, in virtually every country with elections, operate their own versions of polling operations, in collaboration or independently through various applications.

Several organizations try to monitor the behavior of polling firms and the use of polling and statistical data, including the Pew Research Center and, in Canada, the Laurier Institute for the Study of Public Opinion and Policy.
