Copper Face Jacks is looking to reunite people with property they lost at the nightclub before the pandemic.
People are being asked to send a description of the item and the date they lost it to the Dublin club's social media account.
The Harcourt Street venue will then get in touch with instructions on how to collect the item.
Last year its owners, Castleknock couple Cathal and Paula Jackson, put the famous nightclub up for sale.
They were seeking €40 million euro, with Mr Jackson then intending to retire for health reasons.
But they took it off the market in November, saying he felt well enough to stay in the business.
The club has been closed since early in March, and isn't expected to reopen before 2021.
