The service will be operated by Stobart Air, which also operates the Aer Lingus Regional franchise.
Stobart Air pulled out of a plan to sell itself to Dublin-based CityJet last December, bringing a 10-month long process to a bitter end.
Under the planned deal, CityJet would also have operated 18 routes from London Southend Airport, which is owned by the Stobart Group, using four jets based there.
When the merger collapsed, Stobart Air announced a deal with Flybe to operate 12 routes from Southend under a Flybe franchise arrangement. Stobart Air is basing two Embraer E195 jets at Southend to provide the new Flybe services, and it is thought that the planned Southend-Dublin route will also use a jet.
It is understood that plans for the new Flybe Dublin-Southend service are at an advanced planning stage and that it could start operating at the end of October.
