IRELAND’S MOST POPULAR baby names for 2021 have been revealed by the Central Statistics Office (CSO), and a new name has reached the top spot for baby girls. 

For the fifth year in a row, Jack is the most popular name for boys, but Fiadh has overtaken Grace to become the most popular name for girls. 

The top five names for boys were Jack, Noah, James, Conor and Rían, with Liam, Charlie, Daniel, Cillian and Tadhg rounding out the top 10.

The top five names for girls were Fiadh, Grace, Emily, Sophie and Éabha, with Lucy, Mia, Ava, Lily and Ella making up the rest of the top 10.

Jack has held the top spot as the most popular boys’ name since 2007, with the exception of 2016 when James narrowly beat the choice as the most popular name. 

Jack, Conor and James have made the top five since 1998. Noah joined in 2018 after ranking sixth most popular the year before, and has remained there since.

Fiadh has grown in popularity every year since 2009 when it was the 488th most popular girls name. The name ranked third in 2019 and moved to second most popular in 2020.

Grace, Emily and Sophie have been permanent fixtures in the top five names for baby girls every year since 2016.

Not one of the top five names for girls in 2021 appeared in the top 100 names fifty years ago.

In 1971, Mary, Catherine, Margaret, Fiona and Sinead were the most popular names for baby daughters, with 1,907 baby girls named Mary in that year.

In 2021, there were 424 baby girls named Fiadh, 22.2% of the number of girls given the name Mary (1,907) in 1971.
