Andrew O'Connell, Research Now client services director, will head the panel and divide his time between London and Ireland.
Irish Opinions follows hot on the heels of Research Now's 60,000 strong online Australian panel, which launched in September.
Andrew Cooper, managing director of Research Now, said: "Launching Research Now's Irish Opinions now means that consumers in a growing economy at the heart of Europe can now be effectively researched online alongside their European counterparts."
According to Internet World Stats, there are now more than 2m internet users in Ireland, representing 51% of the population.
The panel is open to anyone living in Ireland aged 16 and over.
