Odell was born in Chichester, West Sussex, England, to an airline pilot father and a primary school teacher mother. He has an older sister. He spent part of his childhood in New Zealand because of his father's job. He was educated at Seaford College. He studied piano classically to Grade 7. He began writing his own songs at the age of thirteen but told no one because he felt it was "uncool". At the age of eighteen, Odell abandoned plans to attend the University of York and attempted to gain a place at a music college in Liverpool. He studied at the Brighton Institute of Modern Music playing as part of the band Tom and the Tides before moving to London in 2010.
