Harbour Grace is a town in Conception Bay on the Avalon Peninsula in the province of Newfoundland and Labrador, Canada. With roots dating back to the 16th century, it is one of the oldest towns in North America.

It is located about 90 kilometres (56 mi) northwest of the provincial capital, St. John's. The town has a population of 2,796 (2021), engaged primarily in fishing and fish processing. The alternative spelling of Harbor Grace was current at one time.

The town was named after the French city of Havre de Grâce, which is now known as Le Havre. Harbour Grace was an important port and fishing centre from the earliest days of European exploration of North America. The town was a thriving seasonal fishing community by 1550. The first resident known by name was Robert Tossey of Dartmouth in 1583.

In 1610, pirate Peter Easton made Harbour Grace his headquarters, and established a fort overlooking the bay. Although it was attacked by the French the following year, the early settlement survived throughout the 17th century, with a permanent, year-round population numbering a few dozen, swelling to several hundred during the fishing season.

Around the year 1618, Harbour Grace became a permanent settlement. In that year 1618, Bristol's Society of Merchant Venturers received a charter from King James I of England to establish a settlement near Harbour Grace, "Bristol's Hope", and appointed Robert Hayman as its first Proprietary Governor, a post he held for the next ten years. He was back in London at the end of this period in 1628, where he published a work of pithy epigrams called Quodlibets. He had written this in Harbour Grace;

Over the coming years, control of Harbour Grace became a point of contention between the English and the French. The town, with a population numbering about 100, was razed by the French in 1697, again in 1700, and captured briefly in 1762. Nevertheless, between these attacks, the population grew by 50%. By 1771, the population was close to 5,800. By then, however, other colonial towns along the Atlantic coast had surpassed Harbour Grace in population and influence.

The town continued to grow and peaked in population in 1921, when the census was taken at 11,458 residents.

As trans-Atlantic aviation became more popular in the 1920s and 1930s, many aviation pioneers, among them Amelia Earhart and Thor Solberg chose to make their crossing from the nearby Harbour Grace airfield due to its proximity to continental Europe. Altogether, some twenty flights left Harbour Grace from 1919 to 1936 in their attempts to cross the Atlantic.

In July 1941, the Royal Canadian Navy established a High Frequency Direction Finding wireless station on the airfield. Consisting of an Operations Building and a Direction Finding shack, the station had an uninterrupted sweep of the northern Atlantic sector and was able to provide bearings on U-boat transmissions and to intercept enemy radio traffic.

Harbour Grace was one of the first sites that the Royal Canadian Navy was solely responsible for after war broke out. On May 21, 1945, the Canadian Naval Service approved closing down and disposing of its facility at Harbour Grace. There is no evidence of the station today. Following WWII, the airstrip was left to deteriorate. In 1977, through the efforts of the Harbour Grace Historical Society, it was restored to a usable condition. In 1999, after years of being considered abandoned, the airstrip was reinstated to official international airdrome status under the designator of CHG2.

Today, Harbour Grace continues its tradition as a fishing and fish processing centre. In addition, because of its rich history and many historical buildings, including the 1870 customs house, now the Conception Bay Museum Archived 2018-10-03 at the Wayback Machine, a small tourist industry is emerging. The Gordon G. Pike Railway Heritage Museum and Park (c. 1881–1884) was designated a Municipal Heritage Building in 2006.

In the 2021 Census of Population conducted by Statistics Canada, Harbour Grace had a population of 2,796 living in 1,307 of its 1,483 total private dwellings, a change of -6.6% from its 2016 population of 2,995. With a land area of 33.71 km (13.02 sq mi), it had a population density of 82.9/km (214.8/sq mi) in 2021.
