We present a 0.8–2.5 μm spectrum of the peculiar variable V838 Mon, obtained on 2002 October 29. We see one of the coolest stars — certainly the coolest supergiant — ever observed, with deep water bands and other spectral signatures normally associated with very late L and T brown dwarfs. We suggest that V838 Mon may be the first known ‘L supergiant’.
