Sugar Grove is an unincorporated community located in Watauga County, North Carolina, United States.

Between 1864 and 1865, the home guard battalion of Watauga was stationed at Camp Mast, nearby Sugar Grove.

On February 5, 1865, Camp Mast surrendered, by majority vote, after being surrounded at dawn by a battalion of around 100 Union soldiers, led by Captain James Champion, of Indiana; those who voted for surrender were quickly paroled and discharged.

In 1915, the first cheese factory in the area was established in Sugar Grove (unknown when closed).
