Langford-Juan de Fuca (name from 2017 to 2024) or Juan de Fuca (name from 2009 to 2017) is a former provincial electoral district for the Legislative Assembly of British Columbia, Canada. It was located on the south coast of Vancouver Island, along the Juan de Fuca Strait. It contains the western Victoria suburbs of Langford, Sooke and Highlands.
The electoral district of Juan de Fuca was created in the 2008 redistribution out of the ridings of Malahat-Juan de Fuca and Esquimalt-Metchosin. It was first contested in the 2009 general election, in which New Democrat John Horgan was elected MLA.
It was renamed Langford-Juan de Fuca in the 2015 redistribution and lost some territory to Esquimalt-Metchosin.
A by-election to replace John Horgan took place June 24, 2023.
Under the 2021 British Columbia electoral redistribution that took effect for the 2024 election, the electoral boundaries of Greater Victoria's Western Communities were substantially realigned to add a new district. Langford-Juan de Fuca was divided, with Sooke and the Juan de Fuca communities redistributed to the new district of Juan de Fuca-Malahat while the majority of the district's population in Langford and Highlands redistributed to the new district of Langford-Highlands.
