The Bostik League play-off winners are to take on FC Assyria in March as they show solidarity with refugee community.
The fixture is geared towards the Southwark Refugee Project and the British Red Cross Syria Appeal. All money raised with be split between the causes.
FC Assyria play in the Middlesex County Football League and return after being guests of Hamlet back in 2016.
Two years on from the first refugee awareness game, will be doing the same thing and will hope for a similar result.
Dulwich won the last meeting 3-1 at Champion Hill and the two clubs have had a close bond ever since.
Hamlet manager Gavin Rose has paid tribute to his club’s “one of a kind” supporters after a string of community projects.
Back in 2015 they launched an anti-homophobia in sport campaign and played game against gay world champions Stonewall.
All proceeds from that match, which Hamlet won 6-0, went to the Elton John Aids Foundation.
