"I Will Possess Your Heart" is an alternative rock song recorded by the American band Death Cab for Cutie. The song depicts a one-sided obsessive relationship, which led Paste to name it one of the 25 creepiest songs about love. It is notable for its five-minute instrumental introduction as well as its music video which required location shooting across four continents. The song was the lead single from their sixth studio album, Narrow Stairs (2008).
