St Nicholas Parish Church is a category B listed building and Church of Scotland place of worship in the town centre of Lanark, South Lanarkshire, Scotland. The original 13th-century chapel was documented as early as 1890, however at that time it was claimed that there were no remnants of that building. A survey in the 1990s conducted by the Lanark and District Archaeological Society was able to find artefacts dating back to the 13th century, as well as 16th century pillars believed to have been constructed by Thomas Twaddle in 1571. Sources also reported evidence of the chapel's continued use in the medieval period and post-Reformation.
