Jack and Sarah were the most popular babies' names registered last year, according to the Central Statistics Office (CSO).
Jack has topped the list for the last three years while Sarah has been the most popular name for the last two years.
In total 868 baby boys were named Jack, accounting for 3.1 per cent and 655 or 2.4 per cent of baby girls, were named Sarah.
Jack and Sarah were also the most popular names in five out of the eight regions.
Conor was the most popular boys' name in the Border region, Adam in the Midlands and Sean in Dublin. Ciara was the most popular girls' name in the Midlands, South-East and Border regions.
In general, the top 100 most popular names show that girls are given a wider variety of names than boys.
Sean, Adam, Conor, James, Aoife, Ciara, Emma and Chloe completed the top five lists of boys and girls respectively.
The results are based on an analysis of the first names recorded on birth returns for registration and vital statistics, begun by the CSO in 1998.
