  We report the discovery of four transiting hot Jupiters, WASP-147, WASP-160B,
WASP-164 and WASP-165 from the WASP survey. WASP-147b is a near Saturn-mass
($M_P = 0.28 M_{J}$) object with a radius of $ 1.11 \, R_{J}$ orbiting a G4
star with a period of $ 4.6 $ d. WASP-160Bb has a mass and radius ($ M_p = 0.28
\, M_J $, $ R_p = 1.09 \, R_J$) near-identical to WASP-147b, but is less
irradiated, orbiting a metal-rich ([Fe/H] = 0.27) K0 star with a period of
$3.8$ d. WASP-160B is part of a near equal-mass visual binary with an on-sky
separation of 28.5 arcsec. WASP-164b is a more massive ($M_P = 2.13 \, M_J$,
$R_p = 1.13 \, R_J$) hot Jupiter, orbiting a G2 star on a close-in ($P=1.8$ d),
but tidally stable orbit. WASP-165b is a classical ($M_p = 0.66 \, M_J$, $R_P =
1.26 \, R_J$) hot Jupiter in a $3.5$~d period orbit around a metal-rich ([Fe/H]
= 0.33) star. WASP-147b and WASP-160Bb are promising targets for atmospheric
characterization through transmission spectroscopy, while WASP-164b presents a
good target for emission spectroscopy.
