Harriet Tubman Underground Railroad National Monument, National historical park in Dorchester County, Maryland, United States

Harriet Tubman Underground Railroad National Monument is a protected area in Dorchester County, Maryland, that honors the life of Harriet Tubman and the Underground Railroad. The site covers 480 acres (190 ha) and includes the Jacob Jackson Home site, with landscapes of waterways, marsh vegetation, and low concrete barriers along the water's edge.

The site was first protected as a national monument in 2013 and became a national historical park in 2014. It was established to preserve the landscapes and sites connected to Tubman's life, and a sister park in Auburn, New York, was created later.

The name of the park comes from Harriet Tubman, who was born enslaved in this region and later helped others escape through the Underground Railroad. Visitors can walk through the same flat fields and waterways that shaped her early life, and the landscape itself tells part of her story.

The park is spread across Dorchester, Talbot, and Caroline counties, so a car is helpful to reach its different parts. Some areas are managed with the Blackwater National Wildlife Refuge, and paths can be wet or muddy, so wear sturdy shoes and check local conditions before setting out.

The park is not a single block of land but a collection of sites across three counties, and part of it is managed as a wildlife refuge. The low concrete barrier seen along the water is a reminder that the area is still shaped by water and marsh.
