He was joined by his Dublin counterpart, Naoise O Muiri, for the ceremony at the National Garden of Remembrance at Islandbridge on Saturday afternoon.
They led the tributes to the nearly half a million people from the island of Ireland who served during the First World War - 50,000 of those were killed.
"It is important that along with the Lord Mayor of Dublin I lay a wreath that acknowledges people from the Republic of Ireland and people from the north," said Mr Robinson.
"They collectively spilt blood together and sacrificed themselves for us and it is important that we acknowledge that."
The Queen took part in a similar ceremony and left flowers during her visit last year.
Mr Robinson added: "It is important that we remember and reflect the shared sacrifice."
