Shona Sellers will take over the reins of the school on June 2.
Mrs Sellers, who has held the post of depute head at Inverurie Academy since August 2013, said: “I am very much looking forward to working with the team of dedicated staff at the school.
“And there are many familiar faces there as I’ve taught in the area for a long time.
“I want to provide the best possible quality of educational experience for the young people of Peterhead.
“I recently visited the school and met many pupils. I was very impressed by the young people I spoke to there who were all a credit to Peterhead Academy.
“I am really looking forward to this new challenge.”
The 47-year-old, who attended Ellon Academy, studied chemistry at Robert Gordon University before working as a research scientist at the Macaulay Land Use Research Institute.
After 14 years in the laboratory Mrs Sellers decided to train as a teacher and joined the chemistry department of Fraserburgh Academy.
Education, Learning and Leisure Committee chair, Isobel Davidson, welcomed the news, saying: “I am sure the school communities in Inverurie and Fraserburgh will join me in passing on congratulations and best wishes to Mrs Sellers on her new appointment as headteacher of Peterhead Academy as she has been a dedicated educator in the North-east for several years.”
Mrs Sellers spent 12 years at Fraserburgh Academy, five of which working as a depute head, before taking up her most recent post in Inverurie.
Head of Policy & Resources Education, Learning and Leisure Wilf Weir added: “I extend my very warmest congratulations to Shona and wish her every success for the future.”
