An Indo-Pak Confederation is a concept advocating a political confederation of the sovereign states of Pakistan and India as means of ending bilateral conflicts and promoting common interests in defence, foreign affairs, culture and economic development.

Pakistan however rebutted such concept calling the idea a "mirage," that the partition was irreversible.
