St Andrew, Holborn

St Andrew Holborn was an ancient English parish that until 1767 was partly within the City of London and partly in the county of Middlesex.

In 1723 part of the Middlesex section of the parish became St George the Martyr. This was recombined with the remaining Middlesex portion of St Andrew Holborn in 1767 to create St Andrew Holborn Above the Bars with St George the Martyr. The remaining parish in the City of London was also known as St Andrew Holborn Below the Bars. It was abolished as a civil parish in 1907.
