The International Oil Pollution Compensation Funds (IOPC Funds) are part of an international regime of liability and compensation for oil pollution damage caused by oil spills from tankers.

Under the regime the owner of a tanker is liable to pay compensation up to a certain limit for oil pollution damage following an escape of persistent oil from his ship. If that amount does not cover all the admissible claims, further compensation is available from the 1992 Fund if the damage occurs in a State which is a Member of that Fund. Additional compensation may also be available from the Supplementary Fund if the State is a Member of that Fund as well.

There are at present three IOPC Funds: the 1971 Fund, the 1992 Fund and the Supplementary Fund. These three intergovernmental organisations were established at different times (1978,1996 and 2005 respectively), have different maximum amounts of compensation and have different Member States.
