Signal Hill is a hill which overlooks the harbour and city of St. John's, Newfoundland and Labrador, Canada. The majority of Signal Hill, including Cabot Tower, is designated a National Historic Site. The highest point, Ladies' Lookout, is 167 m high.
Due to its strategic placement overlooking the Narrows, the only entrance to the harbour, fortifications date back to the mid 17th century. On 12 December 1901, the first transatlantic wireless transmission was received there by Guglielmo Marconi.
Adjacent to the National Historic site is the Johnson Geo Centre and Johnson Geo Vista Park.
