Arnprior is a town in Renfrew County, in the eastern portion of Southern Ontario, Canada. It is located at the mouth of the Madawaska River, as it enters the Ottawa River in the Ottawa Valley. The town is a namesake of Arnprior, Scotland, and is known for lumber, hydro power generation, aerospace, farming and its proximity to the national capital region.
In 1823, a 1,200-acre (4.9 km2) surveyed block was ceded to Archibald McNab and given the eponymous name, McNab Township. McNab had approval from the Family Compact to treat the settlers on his land in the feudal manner practiced in Scotland. In 1831 the town was named by the Buchanan Brothers after McNab's ancestral home of Arnprior, Scotland.
Tired of the harsh treatment, the settlers revolted and, after a government investigation, McNab was forced to vacate the area in 1841. Arnprior, Braeside and NcNab township grew as separate communities and boomed when they became incorporated into eastern Ontario's massive timber industry.
One of the most successful businessmen of the upper Ottawa was Daniel McLachlin, who built a massive sawmill at the confluence of the Madawaska and Ottawa Rivers, and expanded the community of Arnprior. The lumber industry maintained a significant position until the closing of the Gillies Mill. One of the most enduring structures of the day was a grist mill built by the Buchanans on the west bank of the Madawaska River. The grey stone building served many purposes after it stopped being used as a grist mill, finally being operated as a restaurant and a gas station, first by the Beattie and then the Baird families, ending in 1974. The facility has been bought by Ontario Hydro prior to the restructuring on the bridge and the creation of a new weir to control the river. The building was consumed by fire in 1976. The forests of the period are represented in the Grove which is an excellent example of indigenous forest, grown after a fire in the 18th century. With individual specimens reaching 175 feet (53 m), these are the tallest white pines in Ontario.
On 8 June 1944 a Castle class corvette, HMS Rising Castle (K494), was re-commissioned as "HMCS Arnprior" until 1946. Arnprior became a recognized name in the numismatic trade. This has a special link to a local employer. In 1955 Playtex ordered some silver dollars for their employees. These coins are later found to show only two and one-half water lines instead of four to the right of the canoe. This variety becomes known as the Arnprior dollar.
The history of Arnprior is preserved and documented at the Arnprior and District Museum  (located in the former post office building and library) and the Arnprior and District Archives, located next door in the basement of the public library. The sandstone building is the defining element in local architecture
The history of Arnprior was documented in popular form by Leo Lavoie, long-time Arnprior resident, in his book, "The Arnprior Story: 1823-1984.
The lumber trade continued in the form of the Gillies sawmill in nearby McNab Township until its closing in 1993. Pictures of the early days of the lumbering industry are seen at the online Charles MacNamara Retrospective.
Kenwood Mills, initially a blanket manufacturer who developed woven fabrics for the pulp and paper industry, was a significant employer in Arnprior and was bought in 1918 by Huyck Corporation. They were a strong contributor to Arnprior remaining viable during the Depression.
Sullivan and Sons and Smith Construction companies, were significant economic drivers and employers based in Arnprior.
The airport at Arnprior was built for the British Commonwealth Air Training Plan and hosted No. 3 Flying Instructor School for the British Commonwealth Air Training Plan. Post War, the facility was used by the Canadian military and a training base known as the Civil Defense College, later known as the Emergency Measures Training Centre.
After the Second World War, companies such as Playtex, Pfizer and Boeing came to Arnprior. Boeing Aircraft Company began manufacturing in 1955 and maintained an operation until selling to Arnprior Aerospace in October 2005.
The Madawaska River at McEwen's Creek was dammed to create a peaking hydro station with approval given in 1972. The dam, which became operational in 1976, has created a new body of water known as Lake Madawaska. This was the fifth and last dam to be built on the Madawaska River and they have a total generating capacity of 614 MW.

Arnprior is served by five schools: three are administered by the Renfrew County District School Board (two elementary schools — Walter Zadow Public School and A. J.

Hockey is the only municipally sponsored sport in Arnprior. The Arnprior Packers represent the town in Eastern Ontario Junior B Hockey League, which is the town's highest level of competition in this sport. The games are played at the Nick Smith Centre which features two year round ice rinks, a 25 metre indoor swimming pool, a fitness centre and a community hall with kitchen. The two ice rinks each have ice surface measuring 200' X 85'. Arena 'A' seating capacity of over 2,000; standing and seated 4,000 capacity. The Nick Smith Centre also plays host to the Chris Finnerty Hockey School.
Curling was established, as an open-air sport in the Arnprior area, around 1865. The Arnprior Curling Club now occupies a 4-sheet building on Galvin Street (est. 1970). The highest level of competition hosted by the club are the Valley League and the Low Cup.

Arnprior is located on the Trans-Canada Highway system, where Highway 417 to the east becomes the two-lane Highway 17 to the west. The town is served by the Arnprior Airport, elevation 109 metres (358 ft) and a nearby floatplane base for general aviation; although there is no longer commercial aviation at the airport.
Arnprior has a long history with railroads. The Canada Central Railway first reached Arnprior on December 6, 1864. On Easter Sunday, March 23, 1880, a change to Standard Gauge brought the Canadian Pacific Railway (CPR) main line. Later the Canadian National Railway (CNR) came and, through the majority of the 20th century, Arnprior was served by both major Canadian railways . The CNR tracks were pulled up and the right-of-way is used as a hiking trail, while the CPR continues to operate through the town. In June 2012 CPR has pulled its tracks throughout the township.
The town is located at the confluence of the Ottawa and Madawaska rivers. It is cut off from the lower Ottawa River and the St. Lawrence Seaway by the Chats rapids, and now the Chats Falls Station. Following exploration, travel and transportation was by canoe: the Ottawa River by Arnprior was a main route for the fur trade.
Anrprior is the start of the River Road that runs in close proximity along the Ottawa River through Braeside, Sand Point to join with Storyland Road.
Arnprior also holds an abundance of wildlife in the town's local forest, the Grove.
Of note are the many walking and biking trails in Arnprior. The Millennium and Macnamara Trails provide scenic views of the waterfront, downtown heritage homes, and two nature trails including a walk-through of the Gillies Grove, a 45-acre (180,000 m2) tract of old growth forest, preserving the white pine which was the foundation of the local lumber industry. Additionally the rivers and local lakes encourage boating, fishing and canoeing.
Galilee Centre, which is the former McLachlin Estate along the Ottawa River, is a holistic spiritual life centre that hosts programs, groups and individuals. On site is a Royal Oak planted in 1860 by His Royal Highness, Edward Prince of Wales.
