Oran Kearney is the new St Mirren manager after being appointed by the club on a three-year deal.
Kearney joins from the NIFL Premiership club Coleraine FC and will take over from Alan Stubbs, who was sacked earlier this week.
The 40-year-old was interviewed for the job before Stubbs was appointed in the summer.
"It's been a rollercoaster 72 hours to be honest. it's all been very surreal," Kearney told the club website.
"I had an interview in the summer that went well and I got a really good feeling about the people in charge at the club. I didn't get the job at that point but I said what's for you won't go by you and here I am.
"There were a few things I had to sort out but I feel at this stage it's the right move for me and I can't wait to get started."
St Mirren won their opening game of the season 2-1 at home to bottom club Dundee but have lost their last three, with a 4-1 defeat at leaders Hearts proving to be Stubbs' final match in charge.
Chief executive Tony Fitzpatrick said: "We are absolutely delighted to have Oran in as our new manager. He is a highly impressive individual and I look forward to working with him."
St Mirren face Celtic on September 14 after the international break.
