St Peter upon Cornhill is an Anglican church on the corner of Cornhill and Gracechurch Street in the City of London of medieval, or possibly Roman origin. It was destroyed in the Great Fire of London in 1666 and rebuilt to the designs of Sir Christopher Wren. It lies in the ward of Cornhill.
It is now a satellite church in the parish of St Helen's Bishopsgate and home of St Helen's 10am congregation, which meets here for regular services on Sunday mornings and for mid-week Bible studies.
