Nine-year-old Mateo Robayna has been fundraising to support research into palliative care for young people with terminal cancers.
The younger brother of teenage photographer Liz Hatton, who died from cancer last year, was among those recognised at the annual BBC Radio York Make a Difference Awards.
Liz Hatton, from Harrogate, died in November from a desmoplastic small round cell tumour after becoming known for her photography bucket list, which even led her to meet the Princess of Wales, Catherine Middleton, last October.
When asked how he felt after being announced as the winner of the Young Hero Award, Mateo said:
"I've never won something like this before.
"I think she (Liz) would be really proud of me being here and raising all the money".
His Mum Vicky added:
"Liz would have been absolutely over the moon.
"To see him recognised after such an incredibly tricky year is just unbelievable. I'm so grateful."
Actress Ella Maisy Purvis, who judged the category, told Mateo in a video message:
"Your courage, bravery and empathy shines through - Liz would be endlessly proud of you and you should be endlessly proud of yourself."
