St Winifred's Roman Catholic Primary School is a Roman Catholic primary school. Opened in 1936, the British school is a part of the Parish of Saint Winifred with Saint Mary in Heaton Mersey, Stockport, England; part of the Diocese of Salford.
In 1980 the school achieved national notability when its school choir released a song that became the Christmas number one single of that year and stayed at the top of the charts for two whole weeks.
Sister Aquinas was the head mistress at the school and had an episode of This is Your Life dedicated to her. Michael Aspel appeared at the school while the choir were recording One Voice with Bill Tarmey (Jack Duckworth from Coronation Street).
The incumbent head mistress is Mrs P. Smith.
