The earliest inhabitants of King's Point were the Maritime Archaic Indians and later the Beothuk Indians.

Prior to the 1860's the area was a source of timber for French fishermen and naval vessels occupying the "French Shore". In the 1860's the first known European settler, James King, established fishing premises and a dwelling, on the Point. This is how the community got its name. His dwelling was destroyed by high tides shortly after, and abandoned by Mr. King.

By 1875, when Alexander Murray (head of the Geological Survey of Newfoundland) did an extensive survey of the area, there were already three or four families settled at King's Point, they lived in carved homesteads out of the virgin forests, which according to Murray grew right to the water's edge. Murray and James Howley, surveyed to the Arm, and laid out lots for a proposed community at King's Point in 1875, and also surveyed a route for a proposed road to Indian River along a route almost identical to the present highway 391. He also predicted King's Point future importance in forestry, agriculture, mining, and pointed out its great tourism potential.

A railway was started around 1908, to carry passengers from Europe (to arrive via steamships) from King's Point to Bonne Bay for transport to the United States. Construction started and four miles of rail bed was built before the project was cancelled after the Robert Bond Government was defeated in a general election.

In 1909, Esau Burt, a local resident, discovered the Randell-Jackman mine. He was cheated out of his discovery by Randell and Jackman, who went on to lose over $40,000 of their money on the mine. A shaft(s) was sunk and ore extracted. Some sources say that no ore was ever shipped, but local sources say that five or six shiploads were shipped from it.

By 1900 there were 15 to 18 families, mostly fishermen and farmers living at King's Point. Mines at Colchester and other locations on the south side of the Arm had closed.

In 1903 the first school opened by the Methodists. The first teacher was Moody Batstone (around 18 years old) from Nippers Harbour.

As early as 1870, King's Point has had a telegraph office. In 1880, it became a repeater station on a line running from the Newfoundland Railway line to Tilt Cove and Bett's Cove. Michael Smart became its first operator. In the early 1900s, fishing and farming were the economic mainstay. A herring canning industry was established by Leonard & Garnett Redman and others with export to Europe. This industry ended prior to 1920. The fishing has never been very important in King's Point since, although there are a few residents today who still depend on it for a living.

As the fishery declined, sawmilling became the main employer. The Thistle family moved in around 1900 and set up a large sawmill and shingle mill, as well as a retail business, on the "Point", which became and remain the major employer until about 1938-1940, when the family moved its operations to Burlington .

From the 1900 to present day smaller sawmills also operated and contributed to the local economy. In the 1940's and 1950's many residents engaged in producing pulpwood for export to Germany. Starting in the 1960's to the present day the production, haulage, and trucking of pulpwood for the papermills at Corner Brook and Grand Falls, has provided the majority of employment to the people of King's Point. Subsistence farming provided part of a living to early residents, and gradually evolved into the commercial farming ventures that are significant contributor to the economy of King's Point and Rattling Brook today.

In 1883, King's Point was served by the Methodist Mission of Little Bay. Later it became the United Church, which still serves the area today. In the 1870's to early 1900's, the Anglican Church served the community but is no longer operating. The first Salvation Army officer was station in King's Point in 1921, and the church is still operating there now. In the 1970’s, the first Pentecostal Church was opened and the Pentecostal Assemblies are still operating today.

The first school was built by the Methodists in 1903. Subsequently, the United Church and the Salvation Army established and operated separate schools here, until the late 1960's, when they amalgamated, to set up Ridgemont Collegiate. Later the system became a part of the Green Bay School District, and since the 1980's Valmont Academy, an all grade school now serves the educational requirements of students in the King's Point - Harry's Harbour area. There is a modern gym, labs, library and other facilities.
