The bookings represent more than 200,000 delegate days and are expected to generate £56.5m for the city's economy.
Most of the events are for the association sector and will take place in 2011, although corporate enquiries were beginning to build, according to CCD communications manager Patricia Sugrue.
The bookings have been described as a significant step towards Ireland's business tourism goal of raising €1bn by 2013.
CCD chief executive Nick Waight said: "This is an extraordinary international vote of confidence in the quality of this world-class facility and in Dublin itself, despite the economic downturn."
Billed as Ireland's first purpose-built convention centre, the CCD will have a capacity of 8,000 delegates spread across 22 meeting tooms, including a 2,000-seat auditorium and 4,500sqm pf exhibition space.
