The 21-year-old joins the Hibs after leaving Wigan Athletic by mutual consent.
Fyvie began his career at Aberdeen before moving to the Latics in 2012 and had loan spells at Yeovil and Shrewsbury last season.
Fyvie said last night: “I’m really pleased to sign for Hibs – as soon as I heard about the opportunity it excited me.
“I was keen to head back up to Scotland and Hibs are a club going in the right direction, so everything about this move made sense.
“My first goal will be to earn a place in the starting line-up and then I want to help Hibs to achieve promotion.
“I can’t wait to get started here at Hibs and I’ve been really impressed with the manager’s vision for the future.”
