Nine-year-old Jessica Saye died on February 15 at her home in Old Town surrounded by her loved ones.
She had been diagnosed with an untreatable brain tumour.
The funeral takes place at St Mary's Church at 12.30pm and is limited in attendance because of coronavirus restrictions.
People are being asked not to gather outside the church but are invited to turn out along the cortege route - adhering to social distancing guidelines - after it leaves the church at around 1.40pm.
It will go down Castle Road, onto Dean Road, then Columbus Ravine and pass Peasholm Park before joining Burniston Road, then Green Lane and Scalby Road before reaching Woodlands Cemetery.
As reported by The Scarborough News, Jessica's family had tried to fulfill the little girl's wishes before she died.
That included helping her to live like a princess for a day and saw her taking a horse and carriage ride from North Bay and along Marine Drive.
Jessica was described by her mother Kelly as “really clever, creative, kind and loving”.
She was a pupil at Friarage Community Primary School.
