Oliver and Charlotte continue to reign supreme as the most popular baby names in 2025 but there are some unexpected, endearing monikers rising up the ranks.

For boys these include Arthur, Arlo and Theodore while for girls they are Luna, Maeve and Hazel.

New analysis by McCrindle Research of the names Australian parents are giving their bubs reveals that for the 12th year in a row, Oliver has taken out the top spot for boys while Charlotte has reclaimed the title of most popular girls name, after intermittently losing it to Isla in the past few years.

The names ranked No.1 both nationally and in South Australia.

Social researcher Ashley Fell says the latest results also firm up Oliver and Charlotte as the most popular names of Generation Alpha, born between 2010 and 2024, with 30,818 Olivers and 24,256 Charlottes.

When it comes to rising star names, Theodore and Hazel are among those to “experience incredible growth in popularity” alongside Arthur, Arlo, Muhammad and Harvey for boys and Luna, Maeve, Florence and Aria for girls.

“Meanwhile, in true Aussie fashion, nicknames continue to be used as first names, with names like Leo (short for Leonardo), Billy (William), Frankie (Frances) and Lottie (Charlotte) becoming popular names of their own,” Ms Fell said.

Today’s most popular boys’ names are Oliver, Noah, Theodore, Henry and Luca while the top five names for girls are Charlotte, Amelia, Isla, Olivia and Mia.

Adorable little Charlotte Rivett, affectionately referred to as “Char-Bear” by her doting parents, dad Zac and mum Katie Bessell, just snuck into Generation Alpha, being born on December 12 – babies from January 1 are Gen Beta.

Katie says it surprised her to learn their precious, one-of-a-kind firstborn is among an era of Charlottes, tipping Harper would be most popular.

“Charlotte was always one of our top names ... I always wanted her name to be able to be shortened into a nickname, so with Charlotte, she could be ‘Char’ or ‘Lottie’,” Katie said.

“Then one of our midwives at Flinders was named Charlotte and she was amazing – we thought ‘that is definitely it’.”
