Meath West is a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas. The constituency elects 3 deputies (Teachtaí Dála, commonly known as TDs). The method of election is the single transferable vote form of proportional representation (PR-STV).
The constituency was created under the Electoral (Amendment) Act 2005 when the previous 5 seat Meath constituency was divided into two 3 seat constituencies of Meath East and Meath West. It was first used at the 2007 general election electing members of the 30th Dáil. The town of Kells was moved to Meath East for the 2011 general election.
The Electoral (Amendment) Act 2009 defines the constituency as:
- "The county of Meath, except the parts thereof which are comprised in the constituencies of Meath East and Louth, and the county of Westmeath, except the part thereof which is comprised in the constituency of Longford–Westmeath."
