13 full-time jobs are to be lost as the Metro Herald and its online version GoMetro.ie print their last editions on Friday 19 December.
According to Paul Crosbie, managing director of publisher Fortunegreen Ltd, the business model has become unsustainable in a difficult advertising environment.
The Metro was launched by Daily Mail publisher DMG Media and The Irish Times in 2005.
The launch was immediately followed by a counter launch of Herald AM from Independent News & Media.
Both media groups made significant losses over the five-year period until the decision to merge the titles into one paper, Metro Herald, in 2010.
