Newton Grove is a town in Sampson County, North Carolina, United States.

[4] Early courthouse records of Sampson County show that the Newton Grove post office was once known as Blackman's Store.

Another post office six miles west of Newton Grove was known as Blackman's Mills from 1858 to 1914.

They were descendants of Jeremiah Blackman, mariner of London who captained several ships that brought English settlers to the Colony of Virginia in the 17th century.

[4] Thirteen Oaks and the Isaac Williams House are listed on the National Register of Historic Places.

There is a six-way roundabout in the center of town, with a hexagonal loop road around it, named Circle Street, contrary to its shape.
