Lakeview is a neighbourhood in Mississauga, Ontario, Canada, centred on Lakeshore Road in the extreme southeastern corner of the city, along the shore of Lake Ontario, between the larger neighbourhood of Port Credit to the west and the Long Branch neighbourhood of Toronto to the east.

Lakeview was known for the 4 Sisters, the four smokestacks of the former Lakeview Generating Station. They were called the 4 Sisters because the generating plant actually had eight boilers and two boilers were 'sistered' to a common stack. The generating station was demolished in 2007, about a year after the four stacks were demolished, which occurred on the morning of June 12, 2006. At 493 feet (150 metres) tall each they were the tallest structures in the area.

Along the shore of Lake Ontario, Lakeview is the home of the Port Credit Yacht Club, Lakefront Promenade Marina, Arthur P. Kennedy Water Treatment Plant, and G. E. Booth (Lakeview) Wastewater Treatment Plant.

The area is also home to the Lakeview Branch Library, and two high schools: Cawthra Park Secondary School, and St. Paul Secondary School. (A third, Gordon Graydon Memorial Secondary School, closed.) Many parks run along Lake Ontario, including lit baseball diamonds used by many junior leagues.

Lakeview is within the Mississauga Purchase of 1806, lands acquired by the Crown from the Mississauga First Nation. Portions of the eastern section of the Lakeview was part of the Colonel Smith Tract, which was added to lands Colonel Samuel Smith had acquired in 1801 in neighbouring Etobicoke. The area later became Toronto Township which was restructured into the Town of Mississauga in 1968.

Lakeview was the site of the Long Branch Armory, which included a rifle range, training facilities and the Long Branch Aerodrome, the first commercial air training airport in Canada. The airport was run by the Curtiss Aviation School, and was located west of the namesake Long Branch neighbourhood in Toronto. The Lakeview location is documented by the presence of Aviation Road running south off Lakeshore Road just west of Cawthra Road. The site is further acknowledged by a historic plaque. The site was home for several arms and munitions manufacturing plants during World War II. One large munitions factory in Lakeview was staffed almost exclusively by women during the war.

The Long Branch Aerodrome was a 100-acre airfield located on Lakeshore Road just west of Dixie Road. The Long Branch Aerodrome has the distinction of being the first Aerodrome in Canada and home to Canada's first aviator training school. It opened on May 20, 1915, by Curtiss Aeroplanes and Motors Company for the Royal Flying Corps. Aircraft such as the Curtiss JN-4 "Jenny" soon became a common sight at the airfield, which included three aircraft hangars.

In January 1917, the newly designated Royal Flying Corps, Canada, the forerunner to the Royal Canadian Air Force, opened the RFC Training Centre at Long Branch. The Long Branch training centre also provided instruction on flying boats at nearby Hanlan's Point on the Toronto Islands, the first seaplane base in Canada. By July 1917, the flight school relocated to the Armour Heights Aerodrome. Long Branch became the Cadet Ground Training School for the Royal Flying Corps. Both the school and the aerodrome closed in 1919. During World War II, the former aerodrome served initially as Non-Permanent Active Militia's No 21 Training Centre and then as an army small arms training centre (Long Branch Rifle Ranges). After the war, the Lakeview Armoury was established on the site but was demolished in the 1950s.
