Ng Wah Catholic Secondary School (also referred to as NWC; Chinese: 天主教伍華中學) is a boys' secondary school in San Po Kong, Wong Tai Sin District, Hong Kong.

Established in 1965 as Sanpokong Catholic College, the school is a government subsidized grammar school for boys, under the sponsorship of the Catholic Diocese of Hong Kong.

On 30 March 1966, the present site in San Po Kong were completed and were inaugurated by the then Governor of Hong Kong, Sir David Trench on 14 April 1966.

In the late 1970s, the rooftop of the secondary school building was modified and became the 6th floor to accommodate the then expanding student population.

In the same year, the three classrooms in the covered playground were converted into a bigger multi-purpose Student Activity Room.
