Millidgeville is a Canadian neighbourhood in the city of Saint John, New Brunswick.
Millidgeville is situated on the northern edge of the city, on Brothers Cove off the Kennebecasis River at the point where that westerly flowing river meets the southerly flowing Saint John River.
The tower of the Royal Kennebeccasis Yacht Club (RKYC) has been a beacon to boaters since its construction at the turn of the 20th century. The Club was founded in 1898. In 1899, The Club published her Constitution, by-laws, sailing regulations, yacht routine, list of members, list of yachts, and signal code
Frederick Neil Broody designed the Royal Kennebeccasis Yacht Club club house in 1901. Royal Kennebaccasis Yacht Club received permission for use of the Prefix Royal and the Blue Ensign. In 1972, the Royal Kennebeccasis Yacht Club, Millidgeville, N.B. was honoured with an 8 cent stamp issued in Canada. In 2004, Herman Sullivan wrote about the Royal Kennebeccasis Yacht Club 'Gone to yacht : a pictorial history of sailing on the St. John River'
The first airplane base in Saint John was the seaplane base across the street from the Royal Kennebeccasis Yacht Club which operated from the early 1920s up until the late 1950s. Saint John's first true airport was built at Millidgeville. It opened in 1930 and was located in the area bounded by Millidge Avenue, Daniel Avenue, Marlin Drive, Woodward Avenue and Boars Head Road. The airport site was chosen because Millidgeville experiences the least amount of fog of Saint John and the surrounding communities. When the new Saint John Airport opened on Loch Lomond Road in the early 1950s there were a lot more complaints of flights being delayed by fog.
