The Municipality of Maciejowice, located in the Masovian Voivodeship within Garwolin County, is an urban-rural municipality with its seat in the town of Maciejowice. In 2004, the municipality had a population of 7,390, which decreased to 6,909 by 2019. The area has a rich history, having previously been part of the rural municipality of Garwolin County in the Siedlce Governorate. In 1870, Maciejowice—which had lost its town rights—was incorporated into the municipality, and in 1939, its territory was expanded by including villages separated from the Świerże Górne municipality.
Covering an area of 172.67 km², the municipality is characterized by picturesque landscapes, with 50% of its land used for agriculture and 37% covered by forests. It is situated on the right bank of the Vistula River and borders the municipalities of Wilga, Łaskarzew, Sobolew, and Trojanów to the north and east, and Stężyca to the south. The regional road 801 runs through the municipality, and railway stations in Sobolew and Łaskarzew provide connections to Warsaw. The local infrastructure also includes a seasonal ferry crossing over the Vistula.
The municipality benefits from a well-developed energy grid, gas supply, and water and sewage systems, contributing to residents' quality of life. Some households still rely on individual heating sources, primarily coal and wood. Maciejowice is socially diverse, with numerous village administrative units (sołectwa) such as Antoniówka, Oblin, Podwierzbie, and Maciejowice itself, as well as non-administrative settlements.
Culturally, the municipality takes pride in its traditions and local events that bring the community together. Despite the population decline, Maciejowice remains a place with a rich history and interesting attractions, supported by functional transportation and infrastructure that benefits both residents and visitors. Representative of rural Masovia, it offers a compelling blend of tradition and modernity.
