The invention provides a circular building curtain wall window. The circular building curtain wall window comprises a circular window frame, and an annular groove is formed in the inner periphery of the circular window frame; inner window glass and outer window glass are arranged in the groove; the outer window glass can only horizontally move along the perpendicular line, and the inner window glass can horizontally move along the perpendicular line and rotate around the perpendicular line; two permanent magnet blocks are arranged at the positions with angle difference being 180 degrees in the circumferential direction of the outer window glass correspondingly, and the permanent magnet blocks face the inner window glass with different magnetic poles; two permanent magnet blocks are also arranged at the positions with angle difference being 180 degrees in the circumferential direction of the inner window glass, and the permanent magnet blocks face the outer window glass with different magnetic poles; and when the same poles of the permanent magnet blocks on the outer window glass and the inner window glass are in an opposite state, the outer window glass and the inner window glass are compressed tightly to the rubber side wall of the annular groove under the effect of magnetic repulsion force; and when the heteropoles of the permanent magnet blocks on the outer window glass and the inner window glass are in the opposite state, the outer window glass and the inner window glass attract to being closed with each other under the effect of magnetic attraction force, so that gaps are left between the outer window glass and the rubber side wall of the annular groove as well as between the inner window glass and the rubber side wall of the annular groove. When the curtain wall window is opened, no displacement towards the interior and the exterior of a room is generated, so that the curtain wall window has relatively high safety and the indoor space is not affected.
