Because parliament needs a two-thirds majority to elect a president in a first round of voting, Speaker Nabih Berri said he had no choice but to reschedule, the Alalam Satellite TV Network reported from Beirut.
Parliament has a Nov. 24 deadline to elect a successor to President Emile Lahoud.
Berri's opposition party and allies are pro-Western and opposed to Syrian influence in Lebanon. Failure to agree on a president could result in two governments, the report said.
Six anti-Syrian influence lawmakers have been assassinated in the past two years. Most recently, Christian party member Antoine Ghanem was killed by a bomb in Beirut last week.
In Damascus, Syria's Al-Baath newspaper said Lahoud supporters insistence on choosing the president meant the government was "pursuing its scheme for Lebanon to fall in the grip of U.S.-Israeli projects."
