A　multi-proxy　quantum　group　signature　scheme　with　threshold　shared　verification　is　proposed.　An　original　signer　may　authorize　a　proxy　group　as　his　proxy　agent.　Then　only　the　cooperation　of　all　the　signers　in　the　proxy　group　can　generate　the　proxy　signature　on　behalf　of　the　original　signer.　In　the　scheme,　any　t　or　more　of　n　receivers　can　verify　the　message　and　any　t　-　1　or　fewer　receivers　cannot　verify　the　validity　of　the　proxy　signature.
