  We report the discovery of WASP-190b, an exoplanet on a 5.37-day orbit around
a mildly-evolved F6 IV-V star with V = 11.7, T_eff = 6400 $\pm$ 100 K, M$_{*}$
= 1.35 $\pm$ 0.05 M_sun and R$_{*}$ = 1.6 $\pm$ 0.1 R_sun. The planet has a
radius of R_p = 1.15 $\pm$ 0.09 R_Jup and a mass of M_p = 1.0 $\pm$ 0.1 M_Jup,
making it a mildly inflated hot Jupiter. It is the first hot Jupiter confirmed
via Doppler tomography with an orbital period >5 days. The orbit is also
marginally misaligned with respect to the stellar rotation, with $\lambda$ = 21
$\pm$ 6$^{\circ}$ measured using Doppler tomography.
