Black Jimmy Pond, also known as Hyles Pond, is an 9-acre (36,000 m) pond in the Cedarville section of Plymouth, Massachusetts. The pond is located northwest of Hedges Pond and northeast of Little Herring Pond.

In 2021, a 3-year-old toddler went into pond, became unconscious, and then was airlifted to Boston Children's Hospital.

Black Jimmy was a counselor at Camp Clark, located on the northern side of Hyles Pond. He was a very personable young man, beloved by the children at the camp. Until one night he killed his wife at the camp. Stricken with regret and fear of being caught, using a picnic table he hung himself on the south side of the pond. His body was found by campers on a nature hike the following day. Since then, many campers have reported seeing the ghost of Black Jimmy's wife in the lodge at Camp Clark.
