The venue has also won the 20th congress of the International Union for Quaternary Science (INQUA) in 2019.
Combined, the events are expected to attract around 5,000 delegates and will provide an estimated £5m (€7m) boost to the Irish economy. They were secured with the help of the Dublin Convention Bureau and Keynote PCO.
C&IT reported in August how The CCD had won five new international association events worth €7m to the local economy.
Nick Waight, CEO of The CCD, said they will be making a "significant infrastructure investment", doubling the venue's wi-fi capacity to facilitate 24,000 devices in time for the five-day DrupalCon, which will see more than 2,000 Drupal developers, site-builders, UX/designers, project managers, business owners and Chief Information Officers come together to learn, share and discuss issues.
Rachel Friesen, events manager Drupal Association, commented: "We are absolutely thrilled to be bringing DrupalCon to Dublin. Drupal has a thriving local community in Dublin and throughout Ireland, and when paired with Dublin's strong tech scene, it created the perfect location for DrupalCon 2016."
The CCD beat off competition from Zaragoza in Spain and Rome in Italy to host the 2019 INQUA Congress, which takes place every four years. It is expected to attract around 3,000 delegates over seven-days with a programme including excursions throughout Ireland, Northern Ireland and parts of the UK.
Catherine Dalton, president of IQUA said: "The congress will showcase the Irish landscape, promote Ireland’s research reputation, facilitate the dissemination of our research activities to a wider audience and attract world-class scientists to the country."
