A by-election was held in the provincial riding of Waterford Valley in Newfoundland on August 22, 2024, to elect a new member of the Newfoundland and Labrador House of Assembly following the resignation of Liberal MHA and cabinet minister Tom Osborne.
The seat was won by Liberal candidate and former Olympic curler Jamie Korab.
Tom Osborne, who had served in the legislature since 1996, resigned as health minister and MHA in July 2024.
Osborne represented Waterford Valley since the riding's creation in 2015. Prior to that, he represented St. John's South which covered part of what is now Waterford Valley. He was a member of the Progressive Conservative Party until becoming an Independent in 2012. In 2013, he crossed the floor to join the Liberals.
Jamie Korab was elected.
