Interstate Oil and Gas Transportation to Europe (INOGATE) was an international energy co-operation programme between the European Union (EU), the littoral states of the Black and Caspian seas and their neighbouring countries.

INOGATE originated in 1995 as an EU support mechanism dealing with INterstate Oil and GAs Transportation to Europe (whence it derived its name as an acronym).

Its webportal contained regularly updated information and news on energy developments in partner countries and relevant EU initiatives and policies.

The programme supported reduction in Partner Countries, their dependency on fossil fuels and imports, improvement of the security of their energy supply, and climate change mitigation.
