Holy Trinity College Bromley (formerly Holy Trinity Convent) was an all-girls infant, junior and senior school from the mid 19th century to December 2005 located in the London Borough of Bromley, England. It was a direct grant aided grammar school until the 1980s when it became purely independent. It was run by the Trinitarian Sisters of Valence order of Roman Catholic nuns along with a sister school in Kidderminster (which reverted to secular control in the 1980s.) The mother house of the Trinitarian order is in France.
