The chief executive of Scottish Enterprise is stepping down after almost eight years in the role.
Lena Wilson said it had been “a real honour and privilege” to head the national economic development agency.
But she said she wanted to “embark on a fresh set of challenges”.
Scottish Enterprise chairman Bob Keiller said she had done “an outstanding job” and driven “a much more international mindset across the whole organisation”.
He added: “A plan to appoint a successor is being developed and details of this will be released in due course.”
First Minister Nicola Sturgeon said Ms Wilson had made a “significant difference” to Scottish Enterprise’s operations in Scotland and on the international stage.
“She has been a committed leader for Scottish Enterprise, a champion for Scottish business and I wish her the best in her future endeavours,” she said.
Economy Secretary Keith Brown also paid tribute to Ms Wilson.
He added: “As we look ahead to developing a new approach to delivering continued economic growth and business support, Lena’s decision to move on at this point will enable a new chief executive to be appointed to take the organisation into a new phase of its work.”
