St Margaret's Academy, Livingston was awarded the Quality Meat Scotland Health and Wellbeing - Hungry for Success award and presented with a trophy, certificate and a cheque for £1,000.
The award acknowledges schools that have worked to ensure school meals are healthy and appealing to pupils, as well as working in partnership with pupils to increase the uptake of school meals within the school.
QMS health coordinator Isobel-Anne Johnston said: "High quality and tasty school meals are critical to children's health and increasingly are seen to help with their educational attainment.
"These awards are an excellent opportunity to highlight schools that are working hard to ensure the success of the Hungry for Success scheme and see food as a major part of the development of their pupils.
"All four schools shortlisted have achieved great success in promoting the health of young people and I would like to wish the finalist schools every success for the future as they build on the great work already achieved."
She added: "They all took a definite whole school approach to Health and Wellbeing and the Hungry for Success initiative. Senior management, pupils, staff, parents and the wider community are all working in partnership towards promoting the health and wellbeing of Scotland's future generations."
