Constantine "Con" Phillips (1746 – 14 February 1811) was a professional cricketer who played for Surrey in the 1760s and 1770s until 1778.
Phillips was born and died in Chelsham, Surrey, and was christened 2 November 1746. Most of his career took place before cricket's statistical record began with regular scorecards in 1772. He made five known appearances in first-class cricket matches between 1773 and 1778.
Phillips was primarily a batsman who scored a known total of 117 runs in 10 innings with a highest score of 31. He has not been credited with any wickets. He took just 1 catch, which suggests he may have been an outfielder.
