Railway electrification in Iran describes the past and present electrification systems used to supply traction current to rail transport in Iran with a chronological record of development, a list of lines using each system, and a history and a technical description of each system. The project is sometimes abbreviated to RAIELEC, in which RAI is the abbreviation of Islamic Republic of Iran Railways (Persian: برقی کردن راه آهن در ایران, abbr: بكرا).
