The 13 British victims of the Kusadasi, Sharm el-Sheikh and Doha bombings will be commemorated at a national memorial.
A service will be held for British bomb victims
The names of the victims will be read out and 13 candles lit in their memory during a service at Southwark Cathedral, London, on 20 September.
Culture Secretary Tessa Jowell, who is in charge of supporting UK victims of terror attacks, said the ceremony would remember survivors and the bereaved.
The service will be led by the Dean of Southwark, the Very Rev Colin Slee.
Ms Jowell said: "Terrorist attacks last year, both at home and overseas, devastated the lives of those who were caught up in them and those who were left behind.
"On 20 September we will remember and pay our respects to the 13 people whose lives were so tragically cut short in Egypt, Turkey and in Qatar.
"And we will also remember those who survived the attacks and those who were bereaved.
"Last year bombers turned family holidays into terror and death.
"It is important that we all take time to reflect and remember the victims of these terrorist atrocities."
Representatives of faith communities, the affected countries and relief agencies will join the families of the bereaved at the service.
