The Gwalia Lateral is a lateral transmission pipeline located in south Western Australia. The lateral is owned and operated by the APA Group. 

The Gwalia Lateral is 5.7 km in length. It delivers gas from the Murrin Murrin Lateral to the Gwalia mine site just south of Leonora. The Gwalia Lateral is part of the Eastern Goldfields Pipeline System (EGPS), which also includes the Eastern Goldfields Pipeline, Gwalia Lateral, Mt Morgans Lateral, Murrin Murrin Lateral and Yamarna Gas Pipeline.
