[en] We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric (e = 0.38) hot Jupiter on a 5.6 day orbit around a V = 12.03, F8 main-sequence host. The host star has a mass and radius of 1.4 ${M}_{\odot }$ and 1.7 ${R}_{\odot }$ respectively. WASP-150b has a mass and radius of 8.5 ${M}_{{\rm{J}}}$ and 1.1 R[SUB]J[/SUB], leading to a large planetary bulk density of 6.4 ρ[SUB]J[/SUB]. WASP-150b is found to be ∼3 Gyr old, well below its circularization timescale, supporting the eccentric nature of the planet. WASP-176b is a hot Jupiter planet on a 3.9 day orbit around a V = 12.01, F9 sub-giant host. The host star has a mass and radius of 1.3 M[SUB]☉[/SUB] and 1.9 R[SUB]☉[/SUB]. WASP-176b has a mass and radius of 0.86 M[SUB]J[/SUB] and 1.5 R[SUB]J[/SUB], respectively, leading to a planetary bulk density of 0.23 ρ[SUB]J[/SUB].
