The new jobs will be in a range of business areas including sales, engineering, and online operations.
All of the roles are expected to be filled by the end of the year.
Facebook already employs 1,300 people at its international headquarters in Dublin.
It recently expanded its office in the Silicon Docks area into the building next door, bringing the amount of space it has in the city to 250,000 sq ft.
The expansion gives the social network the capacity to grow the number of employees in Ireland to 2,000, and today it announced the first tranche of that growth.
In addition, Facebook has also opened a partner centre, the first outside its global headquarters in the US, which is to be used to teach business partners about Facebook's products and services and what may be coming in future.
Head of Facebook in Ireland Gareth Lambe said the expansion demonstrates the company's continued investment here and reaffirms its commitment to Dublin.
The announcement has been welcomed by Minister for Jobs Richard Bruton and IDA boss Martin Shanahan.
