Extra is a Norwegian discount supermarket chain of 574 stores as of 2024.^[1] It is part of the Coop Norge cooperative and was until late 2015 named Coop Extra. The chain markets itself as being low-cost while maintaining large stores with a wide selection of items.^[2] The chain director of Extra is Daniel Kyrre Pedersen.^[3]

Coop Extra was established in 2006, with its first store opening on 15 September in Halden.^[4] The chain expanded rapidly, much of it by rebranding other Coop stores such as Coop Prix.^[5][6] Many Rimi and ICA stores were rebranded to Extra in 2015 when Coop Norge bought up most of ICA AB's Norwegian operations.^[7]

The chain competes mainly on offering lower prices. A price test by VG in 2015 found Extra to be the cheapest chain in Norway overall, albeit only trivially less than REMA 1000.^[8] The chain has its own low price brand, called Xtra, which always is the cheapest alternative.^[9][10]
