A guide joint (1) and a joint orthosis (2) provided with the guide joint for supporting and guiding an anatomical joint (7). The guide joint (1) has a first joint member (3) and a second joint member (4), and the joint members (3, 4) are connected to one another by a first linear guide (5) and a second linear guide (6). Each of the linear guides (5,6) has a guide track (10, 11) formed in the second joint member (4) as a slot or groove, in which in each case a sliding element (12, 13) arranged in the first joint member (3) engages, wherein the guide tracks (10, 11) intersect. The two sliding elements (12, 13) are spatially separate and spaced apart and protrude from a lateral surface of the first joint member (3).
