A hydraulic suspension system 100 including a lockup and roll control valve is provided. The hydraulic suspension system 100 includes a first hydraulic actuator 104 having a first cylinder 180 and a first piston 182 received within the first cylinder 180, and a second hydraulic actuator 106 having a second cylinder 190 and a second piston 192 received within the second cylinder 190. The first cylinder 180 defines a first head chamber 186 and a first rod chamber 188, and the second cylinder 190 defines a second head chamber 196 and a second rod chamber 198, there being a first orifice 210 connected between the first head chamber 186 and the second head chamber 196. The hydraulic suspension system 100 further includes at least one control valve 204 configured to selectively provide fluid communication between the first head chamber 186 and the second head chamber 196 through a second orifice 212, the second orifice 212 being arranged in parallel with the first orifice 210, thereby selectively varying a roll stiffness defined between the first hydraulic actuator 104 and the second hydraulic actuator 106, and at least one accumulator 222, 224 connected to the first head chamber 186 and the second head chamber 196.
