Old St. John's Cemetery (Estonian: Vana-Jaani kalmistu) lies in the southeastern part of Raadi Cemetery in Tartu, Estonia.

It was entered into the National Register of Cultural Monuments on 23 May 1997.

[1] Following a ukase of Russian Empress Catherine II forbidding burials in churches, Old St. John's Cemetery was founded in 1773 under the ownership of St. John's Church, and formally opened on 5 November that year.

It served as the burial location for St. John's German and Estonian congregations and the Tartu Russian church.

[2] However, its name dates to the foundation of New St. John's Cemetery on Puiestee Street.
