John Glover Stone (November 16, 1876 – January 16, 1934)[1] was a boat builder, merchant and politician in Newfoundland.

[3] After his father's death in 1891, Stone and his brother Thomas continued to operate the family fishery supply business.

Because he joined the cabinet of Michael Cashin in 1919, he was considered a traitor by the FPU and was defeated when he ran for reelection in 1919 and 1923.

He was defeated however when he ran for election in Trinity North and returned to his job at the fish curing plant.

He was elected for Trinity North in 1932 as a member of the United Newfoundland Party and was named to cabinet as Minister of Marine and Fisheries.
