Holy Trinity is the Parish church of Haddenham in Cambridgeshire. It provides spiritual care and support to the people of the Parish. Haddenham derives its name from 'Haeda's homestead'.

In 673 it was part of Queen Ethelreda's marriage endowment. A church has stood on the the hill since then as Ovin, Etheldreda's minister and steward, had close connections with the village. The present building is late thirteenth and fourteenth century, but with major a restoration dating to 1876 by R. R. Rowe. The structure is rubble stone and limestone ashlar and dressed limestone with leaded roofs and end parapets with nineteenth century gable crosses.

Mission: Holy Trinity is the Parish church of Haddenham in Cambridgeshire. It provides spiritual care and support to the people of the Parish. The Church of England is called, as are all Churches, to carry forward the work that Jesus Christ began in all aspects of the life of people in society. Jesus said to those who followed him 'As the Father has sent me, so do I send you.' The Mission and Public Affairs division (MPA) oversees how that calling is carried out at the national level of the Church of England in evangelism, development of parish congregations, internationally through the work of the world mission agencies - and in rural and urban situations.
