Popularly known as the Leakin Park, Gwynns Falls Park and Leakin Park, in Baltimore, Maryland, United States, covers 1,216 acres (492 ha)of contiguous parkland, forming the most extensive park in the city. Leakin Park is a wilderness, thickly forested and largely left in its natural state. Baltimore's Department of Recreation and Parks operates Gwynns Falls and Leakin as a single park, beginning at the western edge of the city, following the Gwynns Falls stream from Windsor Mill Road in northwest up to Wilkens Avenue in the southwest.

To the naked eye, Baltimore's Leakin Park is just a 485-hectare stretch of greenery, overshadowed by romantic woodland and a natural forest mostly untouched by humans. Families visit the park to enjoy the steam engines and ponies, and other fanfare. News AU notes that a group of volunteers called Friends of Gwynns Falls/Leakin Park, Inc maintain the park and donate money towards keeping the park's nurture center open.

Leakin Park has a reputation as a dumping ground for the city's murder victims. It has been described as the Baltimore's largest unregistered graveyard. It has risen to worldwide fame in recent years through the phenomenal podcast, Serial. The dead teenager at the center of the true-crime story was found buried in a shallow grave in Leakin Park.

Leakin park's beauty has been blemished by death and crime since the first body was unearthed in 1948. Richard Truman was 13 years old when he was accidentally shot and killed by 15-year-old Robert Clayton Wright, who panicked and buried the teen's body in Leakin Park. That incident unwittingly started a hideous trend which has seen the discovery of 71 bodies as of 2010 listed by Champagne.

Apart from its fame in Serial, the Leakin Park has also been featured in the TV series, The Wire. In one of the episodes, detectives Bunk Moreland and Lester Freamon search the infamous Leakin Park for a body they suspected a drug lord may have buried there. Freamon remembers about a search he previously made in the park. It is where his team was told to only look for bodies matching the description they were given.
