Cocoon stars in the Large Magellanic CloudNear-infrared (JKH) photometry of 13 of the 29 IRAS sources toward the northern LMC that were suggested as possible dust-embedded asymptotic giant branch stars by Reid, Tinney, and Mould (1984) is presented. Two prove to be more luminous LMC red supergiants, while one appears to be a substantially more distant extragalactic object. The remaining 10 are identified as LMC 'cocoon' stars, with most having flux distributions similar to highly reddened Galactic OH/IR sources and bolometric luminosities in the range of -5 to -6. The present estimates of the mass-loss rates imply lifetimes of less than 100,000 yr.
