The route will operate on Monday and Friday from 2 May. Faro is the third route from easyJet to be reinstated since the airline returned to Southend after an absence of almost 18 months. One way fares start from £22.99.
Flights to Palma will start on May 1 and Malaga a day later.
EasyJet announced its intention to return to Southend in December, a month after Ryanair ceased operations there.
Ali Gayward, easyJet’s UK country manager, said: “We are delighted to be able to operate flights to Faro from Southend once again, and provide our customers more choice for next summer.
