The club made the announcement on Thursday afternoon with the former Ibrox favourite returning to the club he played for between 1998 and 2001.
In a rare appearance, van Bronckhorst took to Twitter for the first time since May to express his delight at his appointment.
Tweeting from his verified personal account, @The_real_Gio, the new Rangers boss wrote: “I am very excited and proud to be returning to Rangers as the club’s new manager. I can’t wait to meet all of you!”
His post has sparked a fervent response from delighted Rangers supporters, who had made the Dutchman their overwhelming favourite for the job.
