Tesco, which bought the Quinnsworth, Crazy Prices and Stewarts operations in the Republic and Northern Ireland for £630 million last year, is to take a secondary listing on the Irish stock market.
Trading in Tesco shares begins in Dublin next Monday.
Tesco's main listing is on the London market, where it has a market valuation of £13.8 billion - about a quarter of the value of the entire Irish stock market.
As the primary listing is in London, Tesco - like Diageo - will not be included in the ISEQ Index.
Tesco chief executive Mr Terry Leahy said: "Tesco is committed to delivering good returns to shareholders and a listing on the Irish Stock Exchange will benefit our increasing number of shareholders in Ireland."
Tesco is taking the listing to allow shareholders in Ireland trade their shares more easily.
