Elmworth is a small rural hamlet in northern Alberta, Canada, situated within the County of Grande Prairie No. 1, approximately 68 kilometres west-southwest of Grande Prairie and accessible via Highways 722 and 667. With an estimated population of around 5 residents as of 2023 county assessments, it exemplifies a declining agricultural community that originated from early 20th-century homesteading and now serves as a local hub for education, recreation, and limited industrial activity tied to nearby natural gas production.

The hamlet was settled around 1920 when pioneers established homesteads, a post office, and a general store under the first postmaster, Franklin T. Brewer, fostering a central point for mail and supplies in the Peace Country region. By the mid-20th century, Elmworth developed key community infrastructure, including a school, church, cemetery (established in 1948), curling rink, and community hall, though its population peaked at 30–35 residents before steadily declining due to shifts in farming and rural depopulation. Economically, the area transformed in the mid-1970s with the advent of gas drilling, leading to the construction of the Elmworth Gas Plant—a major sweet gas processing facility that began operations in 1979 and is now operated by Cenovus Energy, employing about 25 people directly and supporting indirect jobs in the region. Adjacent to this is the Elmworth Power Generating Station, operated by Northstone Power Corp., underscoring the hamlet's role in Alberta's energy sector despite its modest size of 0.63 square kilometres. Today, community life revolves around the Elmworth School, which includes a library offering after-school programs, family events, and educational initiatives, alongside recreational facilities like the curling and skating rinks that serve surrounding rural areas.
