The Near Infrared Camera (NIRCam) on the James Webb Space Telescope will provide imaging over a wavelength range of 1-5 microns. To take advantage of the expected stable JWST point spread function and high sensitivity of NIRCam, a simple Lyot coronagraph will be included for high contrast imaging. This will provide NIRCam the ability to detect hot Jovian-mass companions orbiting young (<1 Gyr) stars within 150 pc as well as Jupiters around some of the nearest, low-mass stars. It will also be used to study protostellar and debris disks. We will present the design of the coronagraph and its expected performance based on optical modeling.
