We introduce quantum super-spherical pairs as coideal subalgebras in general linear and orthosymplectic quantum supergroups. These subalgebras play a role of isotropy subgroups for matrices solving Z₂-graded reflection equation. They generalize quantum (pseudo) -symmetric pairs of Letzter-Kolb-Regelskis-Vlaar.
