Who is Sienna Spiro: Is she the next Adele?
Singer-songwriter Sienna Spiro is lighting up the charts with songs such as 'Die on this Hill', and social media users are calling her the next Adele.
Sienna Spiro is one of the fastest-rising singers of 2026, and she is only getting started.
Record producers, fellow musicians and millions of fans all over the world are declaring her the next big thing in music.
Here's why her name is on everyone's lips.
Who is Sienna Spiro?
Sienna Spiro is a British singer-songwriter who is fast becoming the next global superstar. The 20-year-old is only just getting started in the music industry, but she is already making her presence known.
She first started getting noticed on TikTok in 2021, where social media users swooned over her soulful covers. Sienna also gave them a peek inside her writing process, sharing original songs that had fans begging for more.
Her deep alto voice added to the intrigue, and just like that, music lovers were hooked. However, it was only in late 2025, when she released 'Die on this Hill', that people really started to sit up and take notice.
The song quickly went viral on TikTok, with many people sharing their own covers of the track. "I know nothing could matter/ God, I wish something mattered to you," she sings in the famous lyrics.

SZA, Snoh Aalegra and Finneas are among her biggest fans, and they showed the singer some love.
"It was crazy! I was in a writing session, and she commented on a few of my posts and reposted on her story, which at first, I didn't think was real," Sienan said about SZA fangirling over her music.
"I thought it was a glitch on my phone. It was a super surreal moment. I love her and think she’s the greatest and I was just in shock!" she told DAZED.
From relative obscurity to being invited to perform on 'The Tonight Show Starring Jimmy Fallon' and selling out her tour within seconds, Sienna is here to stay.
Sienna Spiro songs
Sienna already has a few Gammy-worthy songs under her belt. Her debut single, 'Need Me', was released in 2024.
"I love this song so much, and I hope you connect with it the way I do. It’s one of the first songs I’ve ever felt truly proud of & I can’t wait for you to hear it," she wrote on Instagram in May that year.
Her most popular song to date is 'Die on this Hill', and her latest single, 'The Visitor', is already making gains on music charts worldwide. Both songs feature on the current Billboard Hot 100 singles chart.
She also has three songs on the UK's Official Singles Chart, including 'Maybe'. Sienna does not have any music on the Top 40 with Danny Painter, but it is only a matter of time before she does.
Sienna has not released an album yet, but her debut EP, 'Sink Now, Swim Later', gave fans a taste of what's to come.
The EP features eight songs, including 'Butterfly Effect', 'You Stole the Show', 'Back to Blonde', 'Taxi Driver' and 'ORIGAMI'.
Is Sienna Spiro the next Adele?
Interview magazine has credited Sienna with bringing the sixties back, calling her the "new age Nancy Sinatra". However, there is one artist she has been heavily compared to - fellow Brit Adele.
"We miss Adele so much. Thank you, Sienna, for filling in and saving today's music industry," one person wrote on YouTube.
Like the 'Heartbreak Anthem Queen', Sienna's 'sad girl music' is full of emotion and soul. "Who hurt this girl?" one TikToker commented on one of her videos.
Sienna has named Amy Winehouse, Frank Ocean, Frank Sinatra, and Etta James among her music influences.
Is she the next Adele? Despite their soulful voices and emotional storytelling, they each have a unique style.
Sienna is forging her own path in the music industry, and the future looks bright.
