The Central Department Store (Bulgarian: Централен универсален магазин, Tsentralen universalen magazin, abbreviated as TSUM) is an upmarket department store in the centre of Sofia, the capital of Bulgaria, officially opened in 1957 and situated in a monumental edifice (part of The Largo complex) on one of the city's main boulevards.

Regent then invested $10.2 million in 1999–2000 to redevelop the property into a mixed-use office and retail building.

TSUM was transformed to become a place for expensive boutiques rather than a store for the people, with the daily number of customers falling to 7,000.

As of 2005[update], world brands like Laura Ashley, Timberland, Nautica, Fila, Fred Perry, Adidas, Mexx, Tommy Hilfiger, Swarovski, Miss Sixty, Nike, Bagatt, Altınbaş and Rossignol had stores in TSUM.

As of early 2023, besides a few stores in the main lobby and restaurants on the ground floor, the building has been emptied of all tenants with the official website marketing it as office spaces.
