Stefflon Don and Tom Walker will receive the 2018 ASCAP (American Society of Composers, Authors and Publishers) Vanguard Award.
The ‘Envy Us’ rapper and the rising singer/songwriter, both 26, will collect their prizes at a star-studded ceremony in London on October 23.
Stefflon – whose real name is Stephanie Allen – said: "So excited to win this award. Music is my passion and to be given this award and be recognised by ASCAP for something I love is incredibly overwhelming.
"A massive thank you! Shout out to all my DONS – don’t you ever stop believing in yourself."
‘Leave A Light On’ hitmaker Tom added: "This year has been absolutely amazing for me and to win this award for songwriting really means a lot. I am so grateful for the support from my fans and ASCAP, and I can’t wait to celebrate on the night!"
On the night, prizes for Song of the Year, Top Digital Song, Top EDM song and Film Score of the Year will also be dished out.
Paul Williams, president of ASCAP and chairman of the board, said: "Stefflon Don and Tom Walker are self-made firebrands paving the way for the British music scene.
"Whether through their solo works or collaborations with the biggest hitmakers the world has to offer, both artists have truly set an unbeatable standard in their dedication to authentic, honest songwriting.
"We are so honoured to celebrate Stefflon and Tom’s chart-topping and globe-trotting careers, and look forward to watching them take off in Europe and beyond."
Dua Lipa and The Amazons won the Vanguard Award last year.
Previous recipients of the accolade include the likes of Jess Glynne, MNEK, Kendrick Lamar, Calvin Harris, Walk The Moon and Diplo.
The honour recognises the impact of outstanding ASCAP members on musical genres that will help shape the future of music.
