HMCS Norsyd was a modified Flower-class corvette that served with the Royal Canadian Navy during the Second World War. She served primarily in the Battle of the Atlantic as a convoy escort. She was named for North Sydney, Nova Scotia, her name being a contraction of the city's name. This was due to a naming conflict with a Royal Australian Navy vessel. After the war she served as a merchant ship and then as a corvette in the Israeli Navy.
