For a vacuum valve comprising a valve housing (1) with a valve opening, a valve seat surrounding the valve opening, a closing element (9), and at least one peripherally closed seal (10, 11) that is arranged on the closing element (9) and has first and second seal main sections (14, 15) and first and second seal connecting sections (16, 17) allocated to first and second seat main sections arranged offset relative to each other in a direction of the axis (3) of the valve opening (2) and first and second seat connecting sections, is provided, with the seal extending in a groove that is defined, when viewed in cross section, by two side walls and a base wall. The first seal main section (14) is arranged on a front end face (18) of the closing element (9) with respect to the closing direction (8) of the closing element and has a middle part (19) in which the seal (10, 11) extends in a straight line. The seal (10, 11) is clamped by a clamping bar (23) at least across a first sub-region (22) of its longitudinal extent lying in the middle part (19) of the first seal main section, with the clamping bar being fixed on the closing element (9) and forming one of the two side walls of the groove. Through at least one second sub-region of the longitudinal extent of the seal (10, 11), the two side walls and the base wall defining the groove are formed by the closing element (9).
