Humboldt Park, one of 77 designated community areas, is on the West Side of Chicago, Illinois. The Humboldt Park neighborhood is known for its dynamic social and ethnic demographic change over the years. The Puerto Rican community has identified strongly with the area since the 1970s; Humboldt Park is also the name of a 207-acre (0.8 km²) park adjacent to the community area.

The official community boundaries established by the City of Chicago include Bloomingdale Ave to the north, the Union Pacific railroad tracks to the south, the train tracks running between Kostner and Cicero to the west, and Humboldt Park proper to the east (to the East side of California Ave).

In contrast to the Humboldt Park Official Community Area, the Humboldt Park Neighborhood’s borders include Western Avenue to the east, Pulaski Road to the west, North Avenue to the North, and the Union Pacific tracks to the south. The railyards southeast of Grand and Sacramento are also part of the community area. There are two distinct areas of Humboldt Park (the neighborhood): East Humboldt Park (In the West Town Community Area) and West Humboldt Park (In the Humboldt Park Community Area), divided by Sacramento Boulevard.
