We report the discovery by WASP of five planets orbiting moderately bright ($V$ = 11.0-12.9) Solar-type stars. WASP-137b, WASP-143b and WASP-146b are typical hot Jupiters in orbits of 3-4 d and with masses in the range 0.68--1.11 $M_{rm Jup}$. WASP-134 is a metal-rich ([Fe/H] = +0.40 $pm$ 0.07]) G4 star orbited by two warm Jupiters: WASP-134b ($M_{rm pl}$ = 1.41 $M_{rm Jup}$; $P = 10.1$ d; $e = 0.15 pm 0.01$; $T_{rm eql}$ = 950 K) and WASP-134c ($M_{rm pl} sin i$ = 0.70 $M_{rm Jup}$; $P = 70.0$ d; $e = 0.17 pm 0.09$; $T_{rm eql}$ = 500 K). From observations of the Rossiter-McLaughlin effect of WASP-134b, we find its orbit to be misaligned with the spin of its star ($lambda = -44 pm 10^circ$). WASP-134 is a rare example of a system with a short-period giant planet and a nearby giant companion. In-situ formation or disc migration seem more likely explanations for such systems than does high-eccentricity migration.
