The Princess Mary Maternity Hospital was a health facility in Jesmond, Newcastle upon Tyne.

[2] Lying-in is an archaic term for childbirth (referring to the month-long bed rest prescribed for postpartum confinement).

[3] The Lying-in Hospital moved to a purpose-built facility in New Bridge Street designed by John Dobson in 1826.

[a][2] After the Lying-in Hospital in New Bridge Street was deemed inadequate, a new facility was built in Jubilee Road and officially opened by Princess Mary as the Princess Mary Maternity Hospital in 1923.

[2] During the Second World War the hospital moved to the old home of the Northern Counties Orphans' Institution in Jesmond.
