McAdam is a village in southwestern New Brunswick, Canada, located in York County near the Canada–United States border. The community is situated within a predominantly forested part of the province, surrounded by the lakes, rivers and rural landscapes characteristic of inland New Brunswick. Its location places it relatively close to the border with the state of Maine in the United States, with the surrounding region forming part of the broader Appalachian landscape of northeastern North America.

The history of McAdam is closely connected to the development of the railway in New Brunswick. The village grew as an important railway community and junction, with rail connections linking the area to destinations across New Brunswick and beyond. McAdam Railway Station became a significant local landmark and remains an important reminder of the community's railway heritage. The station and associated railway infrastructure played an important role in the movement of passengers and goods through southwestern New Brunswick.

Today, McAdam is a small rural community surrounded by extensive woodland and natural areas. The village retains elements of its railway-era character while serving as a residential community within the wider York County region. Its position near the international border and its historic connection to the railway give McAdam a distinctive place within New Brunswick's transportation and settlement history.

The surrounding landscape reflects the changing seasons of eastern Canada, from green forests and warmer summer conditions to autumn foliage, winter snow and the changing weather of spring. McAdam provides a view of a quieter side of New Brunswick away from the province's larger urban centres, with its natural surroundings and historic railway heritage forming an important part of the area's identity.
