The Veronicas are an Australian pop duo from Brisbane. The group was formed in 2004 by identical twin sisters Lisa and Jessica Origliasso.

In 2005, the Veronicas released their debut studio album, titled The Secret Life of..., which peaked at number two on the Australian Album Chart and was certified 4× platinum by Australian Recording Industry Association (ARIA) for selling over 280,000 copies. The album spawned five singles, led by "4ever", three of which were top ten singles in Australia. In 2007, the duo released their second studio album, Hook Me Up, which also peaked at number two in Australia and was certified 2× platinum for selling over 140,000 copies. The album garnered four Australian top ten singles. The album's title track, "Hook Me Up", was the Veronicas' first number one single in Australia, while "Untouched" was an international top-ten hit, especially in Sweden, where it topped the chart for seven weeks.

Following a lengthy hiatus (broken only by the July 2012 release of the Australian top-40 single "Lolita" and various gigs for their fans), in September 2014, the Veronicas released "You Ruin Me", the first single from their self-titled third studio album. The song debuted at number one on the ARIA chart, becoming the women's second chart-topping single and their first to debut in the top spot. It also charted in United States and United Kingdom. The album was released both physically and digitally on 21 November 2014. In 2016, they hosted the ARIA Music Awards. They spent most of the period between 2016 and 2021 releasing gold and platinum singles in Australia, leading to the release of both their fourth and fifth albums, Godzilla and Human, in May and June 2021, respectively.

The duo's MTV reality show The Veronicas: Blood Is for Life premiered in November 2019. In 2021 the sisters competed as contestants on the fifth season of The Celebrity Apprentice Australia.

In November 2022, they signed with the label Big Noise. Their sixth album Gothic Summer was released in March 2024.
