Thomas Ross (1614–1679) was a seventeenth-century Scottish preacher and a dedicated supporter of the Scottish Reformation. He lived and worked during a turbulent era of religious conflict in Scotland, where his theological convictions placed him in direct opposition to the reigning monarch. Ross famously refused to submit to the episcopal church government established by the King of England, a decision that resulted in his expulsion from his official church position in 1662.
Following his expulsion, Ross refused to be silenced and continued to preach as a Covenanter, holding unlawful religious services. His persistent nonconformity and illegal preaching eventually led to his arrest by authorities in 1675. After being imprisoned for two years, Ross was finally released on bail in 1677. He returned to his home, where he passed away a few months later in 1679, remaining committed to his Presbyterian principles until the end of his life.
