General elections were held in Lebanon on 6 May 2018. Although originally scheduled for 2013, the election was postponed three times in 2013, 2014 and 2017 for various reasons, including the security situation, the failure of the Parliament to elect a new President, and the technical requirements of holding an election. A new electoral law adopted in 2017 provides a proportional representation system for the first time.

The Lebanese Parliament is the national parliament of the Republic of Lebanon. There are 128 members elected to a four-year term in multi-member constituencies, apportioned among Lebanon's diverse Christian and Muslim denominations but with half of the seats reserved for Christians and half reserved to Muslims per Constitutional Article 24. Lebanon has universal adult suffrage. Its major functions are to elect the President of the republic, to approve the government, and to approve laws and expenditure.
