Albert Pellew Salter (1816–1874) was a provincial land surveyor in Upper Canada then Ontario in the mid-19th century. He is historically most notable for having discovered magnetic abnormalities at what is now Creighton Mine in Greater Sudbury, while surveying a baseline westward from Lake Nipissing in 1856. Salter died in 1874. Salter's Meridian is commemorated by a historical plaque in the Naughton neighbourhood of Sudbury.
