Marystown is a town in the province of Newfoundland and Labrador, Canada, with a population of around 5,000. Situated 306 km from the province's capital, St. John's, it is on the Burin Peninsula. Until the early 1990s, its economy was largely based on shipbuilding, and it is due in part to this that the town experienced a population increase of 295% in just over a decade. The town was also dependent on the fish plant for employment.

Though the shipyard still holds a presence in the town, residents have had to look elsewhere for economic subsistence in the last decade or so. The closure of the fish plants in Newfoundland has also had its hand in the decline in economic subsistence. Mortier Bay also served a strategic role during World War II, and was the site selected to evacuate the Royal Family and regroup the British Navy in the event of German invasion of Britain. Currently fish farming and the shipyard remain important to the local economy; in fact, construction of the world's largest fish hatchery, the Grieg NL project, began at the town in 2019.

Marystown lies on hummocky pyroclastic volcanic rock of mixed composition. This rock is overlain by very stony sandy loam glacial till which has a classic podzol soil profile in undisturbed areas; this is named as Toslow soil association. The vegetation at the time of the soil survey was a barren dominated by sphagnum mosses, heath-type shrubs, and mountain alder. Forest vegetation, mostly of coniferous trees, has developed in many areas around town as can be seen on Google Street View.

In the 2021 Census of Population conducted by Statistics Canada, Marystown had a population of 5,204 living in 2,328 of its 2,609 total private dwellings, a change of -2.1% from its 2016 population of 5,316. With a land area of 62.23 km (24.03 sq mi), it had a population density of 83.6/km (216.6/sq mi) in 2021.

While the town contains a diverse mixture of churches of varying denominations, the town is almost entirely Christian. The information presented from a 2001 census from Statistics Canada indicates that 68% of the population is Roman Catholic.

Established in 1910, the original edifice, constructed in the early 1900s, had to be reconstructed in the late 1970s due to a fire. In more recent years, the church has received much attention from the news when a family of illegal immigrants from Israel resided there as a place of sanctuary. Alexi and Angela Portnoy and their five children (the three youngest of whom were born in Canada) stayed in the church's basement for a total of 962 days while seeking citizenship status. The family was ultimately deported to Israel, but their supporters vowed to try to help the family to return.

Establishment of the church began in 1956. The first Pentecost church in Marystown was officially completed in 1958. Since then there have been three Pentecost churches erected in the Marystown area: the original edifice in 1958, the second in 1974, and the current church that was built in 1995.

The Seventh Day Adventists established a significant population in Marystown in the 1970s. The construction of the first church began in 1985 along with a Seventh-Day school. Though the construction was completed much earlier, 1987 denotes the official church opening.

By 2018, it was recognized that the region exhibited significant unemployment; further, the potential workforce was not sufficient to support shipyard and aquaculture expansions envisioned in subsequent years. This led to a call for loosening immigration regulations so that the workforce could be expanded with immigrant workers.

Shipyard workers are represented by at least two unions, Marine Workers Federation - Unifor Local 20 and the Marine Office and Technical Employees Unit.

Shipbuilding began in Marystown not long after it was settled in the early 1800s. The earliest records of shipbuilding in the area date to 1908, and Marystown's first shipyard was constructed in 1918 north of the town.

The Marystown Co-operative shipyard opened in 1939 was destroyed by fire in 1941; originally committed to building fishing trawlers, it was converted to minesweeper construction for World War II. Work at the site began in 1938 when the Newfoundland Commission of Government established the first government shipyard. The Marystown Shipyard was established by the Newfoundland government in 1959 for the construction of longliners, "motor-powered decked vessels ranging from 35 to 65 feet in length." This facility was operated as a Crown Asset until the 1980s, when it was privatized.

Construction of a nearby additional shipbuilding facility began in 1966 and it was opened in 1967 by the shipping company Canadian Vickers, initially for the construction and repair of fishing vessels. This facility has changed owners and names over the years; the initial owner was Newfoundland Marine Works Ltd., until 1973. Ownership changed hands to Marystown Shipping Enterprises Ltd., which held title until 1978, when ownership changed to Marystown Shipyard Ltd. In response to a decline in the cod fishery industry, the Newfoundland government refurbished the shipyard in 1992. Ownership left Canada when the American company Friede Goldman Ltd. bought the facility in 1998, and remained in American hands when ownership changed again in 2002 to Kiewit Offshore Services Ltd. By 2019, the shipyard had been idle for four years and was acquired by Marbase Marystown Inc. (usually just Marbase), under a 20-year lease with the intention of establishing a service hub supporting regional aquaculture, the first of its kind in Canada. Marbase is a partnership between one Newfoundland businessman, Paul Antle, and the Norwegian company Amar Group AS.

In 2019, Marbase Cleanerfish Ltd., began work on a commercial lumpfish hatchery in Marystown, with an anticipated customer base of Atlantic salmon farm operators. As of 2020, government approval of the work in relation to environmental impact had not yet been completed.

For many years, the fish plant in Marystown created hundreds of jobs in the small town. Originally operated by Fishery Products International (FPI) the plant was sold to Ocean Choice International (OCI) in 2007. In 2011, the plant employed roughly 240 people seasonally. In November 2011, provincial government-appointed auditors backed up claims by OCI that they were losing millions of dollars each year operating the fish plant. On 2 December 2011, the company announced that they would permanently close their Marystown and Port Union fish plants and invest money into other plants in the province. Demolition of the plant began in 2015.
