The former One Direction member will perform at Wolverhampton Racecourse after a day of racing on August 22.
There were huge queues for tickets last time Liam performed in Wolverhampton - with One Direction at the Civic Hall back in December 2011.
And with a capacity of 20,000, there will be plenty of space for fans to watch the summer show at the racecourse in Dunstall Park.
Tickets go on general sale on Friday, with entry costing £35 for adults, £25 for children and under-fives going in free. Entry includes access to the Saturday afternoon of racing which starts at 2.20pm before the music begins at 6.30pm.
Today's announcement follows the release of the 26-year-old's debut solo album, LP1, in December.
Liam, from Bushbury, first rose to fame as a teenager alongside Harry Styles, Niall Horan, Zayn Malik and Louis Tomlinson in boyband One Direction.
Formed during the fifth series of The X Factor in 2008, the five-piece group went on to embark on four world tours, sell 50 million records worldwide, and win a series of accolades including Brit Awards, MTV Music Video Awards, Billboard Music Awards and more.
The band then went on a hiatus in 2016, with Liam going on to release his first solo single, Strip That Down, in 2017.
The former St Peter's Collegiate School student was in a relationship with singer Cheryl from 2016 until the start of 2018 and the couple share a two-year-old son, Bear.
He regularly returns to Wolverhampton and has donated thousands of pounds to The Way Youth Zone in the city.
In 2018 Liam released steamy single For You with Rita Ora and the couple performed the song at the Brits.
His first solo album LP1 was released in December and features a range of songs, including Strip That Down, Polaroid, Bedroom Floor, Stack It Up and more.
However the album suffered poor reviews and peaked at number 17 in the album charts.
And it has now been revealed that Liam has been snubbed for a Brit Award, while former One Direction bandmate Harry Styles has been nominated in two categories.
Despite missing out on a nod, Liam performed during a special ITV broadcast, called The Brits Are Coming, during which the nominations were announced.
Tickets go on "artist pre-sale" and pre-sale for O2 customers at 10am on Wednesday before general sale begins at Friday on 10am here.
The racecourse regularly holds post-racing concerts with recent performers including Madness, Jess Glynne and The Kaiser Chiefs.
Parking costs £10 and all tickets will be subject to a booking fee.
