St Kentigern's Church is a scheduled monument in Lanark, South Lanarkshire. It is believed that the church was founded by St Kentigern himself shortly before his death in 603 AD. There is documentary evidence of its existence, however, dating back to 1150 AD when King David I granted it to the monastery of Dryburgh. Pope Gregory VIII took the church into his own protection in 1228.
The architecture of the present church is 13th century and the site is known to have been occupied by a previous church. The church, which was once attended by William Wallace, is now in a state of disrepair, despite having had repair work completed recently.
