Livingston manager David Hopkin has made his sixth summer signing after recruiting versatile defender Mikey Miller from Morton.
The 21-year-old, who can also play in midfield, joins the Lions after making 48 appearances in two seasons at Cappielow.
The former Scotland Under-20, 19 and 18 internationalist was also a member of the Ton side that clinched the League One title in 2015.
Hopkin, who has already signed up Shaun Byrne, Sean Crighton, Alan Lithgow, Nicky Cadden and Jordan Sinclair for next term, said: “I’m absolutely delighted Mikey has chosen to sign with Livingston.
“He’s a fantastic player and a superb addition to our ranks, and we all welcome him to the club.”
