A filibuster is a process, typically an extremely long speech, that is used primarily to stall the legislative process and thus derail a particular piece of legislation, rather than to make a particular point in the content of the diversion per se. The term first came into use in the United States Senate, where senate rules permit a senator, or a series of senators, to speak for as long as they wish and on any topic they choose.

Under Senate rules, the speech need not be relevant to the topic under discussion, and there have been cases in which a senator has undertaken part of a speech by reading from a telephone directory. Legendary segregationist Senator Strom Thurmond set a record in 1957 by filibustering the Civil Rights Act of 1957 for 24 hours and 18 minutes. Thurmond broke the previous record of 22 hours and 26 minutes set by Wayne Morse (I-OR) in 1953 protesting the Tidelands Oil legislation.

Filibusters have become much more common in recent decades. Twice as many filibusters took place in the 1991-1992 legislative session as in the entire nineteenth century. (Frozen Republic, 198)

Until 1917, there was no formal mechanism to allow the senate to close debate, and any senator could start a filibuster. From 1917 to 1949, two-thirds of those voting could limit debate on a measure. As civil rights loomed on the Senate agenda, this rule was revised in 1949 to allow cloture on any measure or motion by two-thirds of the entire Senate membership; in 1959 the threshold was restored to two-thirds of those voting. After a series of filibusters in the 1960s over civil rights legislation, the Senate revised its cloture rule so that three-fifths of the Senate (usually 60 senators) could limit debate. Despite this rule, the filibuster or the threat of a filibuster remains an important tactic that allows a large minority to affect legislation.

Filibusters do not occur in legislative bodies in which time for debate is strictly limited by procedural rules, such as the United States House of Representatives.

In current practice, Senate rules permit procedural filibusters, in which actual continuous floor speeches are not required, although the Senate majority leader may require an actual traditional filibuster if he so chooses.

The 1939 film Mr. Smith Goes to Washington climaxes with a young senator, falsely accused of corruption, staging a filibuster in order to forestall his expulsion from the chamber.

A unique form of filibuster was pioneered by the Ontario New Democratic Party in the Legislative Assembly of Ontario in April, 1997. To protest Progressive Conservative government legislation that would create the megacity of Toronto, Ontario, the small New Democratic caucus introduced 11,500 amendments to the megacity bill, created on computers with mail merge functionality. A typical NDP amendment would name a street in the proposed city, and provide that public hearings be held into the megacity with residents of the street invited to participate.

The Ontario Liberal Party also joined the filibuster with a smaller series of amendments; a typical Liberal amendment would give an historical designation to a named street. The filibuster occupied the legislature day and night for approximately ten days, members alternating in shifts. On the fifth day, tired and often sleepy government members inadvertently let one of the NDP amendments pass, and residents of Cafon Court in Etobicoke, Ontario were invited to a public consultation on the bill.
