Henfield Rock is an offshore rock lying northwest of Robert Island in the South Shetland Islands, Antarctica. It was known to the early 19th century sealers operating from nearby Clothier Harbour, and sometimes included under the name 'Powels Islands' or 'Heywood Islands'.
The feature is named after Captain Joseph Henfield, Master of the American sealing vessel Catharina that visited the South Shetlands in 1820–21.
