Total numbers at overseas companies now stands at 187,056
The number of people employed in IDA Ireland firms - the Government agency responsible for attracting foreign direct investment - has hit a record high.
The IDA says it has seen a 66% year-on-year rise in job creation, adding 12,000 net posts.
Total employment at overseas companies now stands at 187,056 people - the highest level in its 67 year history.
IDA client companies created just under 19,000 jobs on the ground during the year across a range of sectors - with every region posting net gains.
Net jobs stood at 11,833 compared to 7,131 in the same time period last year.
This means that more than one-in-five private sector jobs in the economy are from IDA-supported foreign direct investment.
While the number of investments secured during the year rose to 213 from 197 in the previous year.
And the number of new name investments went to 94 from 88.
Chief executive officer of IDA Ireland, Martin Shanahan, said: "The contribution of the FDI sector has always been important to Ireland, but the 2015 results show that the contribution has never been larger".
"It is particularly welcome to see such a broad-based performance with all industry sectors and all regions growing".
"Many of the projects won in 2015 were capital intensive, and provided strong additional benefits beyond the jobs themselves", he added.
Among investments secured during the year were:
