  We report the discovery, from WASP and CORALIE, of a transiting exoplanet in
a 1.54-d orbit. The host star, WASP-36, is a magnitude V = 12.7, metal-poor G2
dwarf (Teff = 5959 \pm 134 K), with [Fe/H] = -0.26 \pm 0.10. We determine the
planet to have mass and radius respectively 2.30 \pm 0.07 and 1.28 \pm 0.03
times that of Jupiter.
  We have eight partial or complete transit light curves, from four different
observatories, which allows us to investigate the potential effects on the
fitted system parameters of using only a single light curve. We find that the
solutions obtained by analysing each of these light curves independently are
consistent with our global fit to all the data, despite the apparent presence
of correlated noise in at least two of the light curves.
