The Keyham Barton Roman Catholic Senior Mixed, Junior Mixed and Infants' School was situated in Ocean Street, Keyham, Plymouth.

Run by the Sisters of Charity of Saint Paul, the School was opened on Monday April 2nd 1906 although it took until June 20th 1906 for it to become properly equipped for its role.

This was in spite of Devonport Borough Council resolving on May 12th 1904: 'That this Council, after full consideration and discussion, unanimously endorses the action of the Education Committee in its opposition to the proposed Roman Catholic School in the Keyham Barton district, or any other denominational school in the Borough'.  Curiously the School was not even in the Keyham Barton district anyway.

The School came under the Devonport Local Education Authority on and as from January 1st 1907, when it became the Keyham Barton Roman Catholic Elementary School*.
