The Ireland Palestine Solidarity Campaign is urging a boycott of Israeli products and services - saying Palestine must not be forgotten.
Two members of the Gaza Freedom Flotilla will be holding a public meeting at the Central Hotel on Exchequer Street in Dublin this afternoon at 2pm.
Fintan Lane and Derek Graham were on board different ships intercepted by Israelis while trying to deliver humanitarian aid to Gaza.
The IPSC is also hoping to highlight what it calls the complicity of Veolia, the operators of the Luas in Dublin, with Israel's regime.
A spokesperson for the Irish Anti-War Movement said: "It is vital the murders of peace activists trying to break the siege of Gaza, and most importantly the cruel siege itself are not forgotten and that Israel is held to account for what it is doing to the Palestinian people.
"The easiest and most concrete way, ordinary people can put pressure on Israel and show their solidarity with the Palestinian people is by supporting the campaign of boycott, sanctions and divestment.
"Today we want to make the shops and shoppers in Dublin city aware of the connection between Israeli atrocity and some of the goods stocked in Dublin shops, and appeal to them not to buy these goods or stock them.
"Israel does very significant trade with Ireland. We need to hurt Israel in the pocket if we are to put pressure on them to end their cruel oppression of the Palestinian people."
