The Lancashire Fusiliers War Memorial is a First World War memorial dedicated to members of the Lancashire Fusiliers killed in that conflict. Outside the Fusilier Museum in Bury, Greater Manchester, in North West England, it was unveiled in 1922—on the seventh anniversary of the landing at Cape Helles, part of the Gallipoli Campaign in which the regiment suffered particularly heavy casualties. The memorial was designed by Sir Edwin Lutyens. Lutyens was commissioned in light of a family connection—his father and great uncle were officers in the Lancashire Fusiliers, a fact noted on a plaque nearby. He designed a tall, slender obelisk in Portland stone. The regiment's cap badge is carved near the top on the front and rear, surrounded by a laurel wreath. Further down are inscriptions containing the regiment's motto and a dedication. Two painted stone flags hang from the sides.

The memorial was unveiled by Lieutenant General Sir Henry de Beauvoir De Lisle on 25 April 1922, using the novel method of pressing an electric button. The remaining funds were spent on drums and bugles for the regiment and donated to the Lancashire Fusiliers' compassionate fund. After the Lancashire Fusiliers were amalgamated into the Royal Regiment of Fusiliers in 1968, the memorial was adopted by the new regiment and rededicated to all fusiliers killed in action. It originally sat outside the Lancashire Fusiliers' headquarters in Wellington Barracks but was relocated when the barracks closed in the 1970s. It was moved again in 2009, this time to sit in a public park renamed Gallipoli Gardens, outside the Fusilier Museum, which moved at the same time. The memorial was designated a grade II listed building in 1992. It was upgraded to grade II* in 2015 (on the centenary of the Cape Helles landing), along with two other memorials related to the Gallipoli Campaign; later that year it was recognised as part of a national collection of Lutyens' war memorials.
