Jan Potmesill (b. March 31, 1966, Prague, Czechoslovakia) is a Czech actor.

In summer 1989, he finished his lectures at the Theatre Faculty of the Academy of Performing Arts in Prague and joined Divadlo na Vinohradech. Later that year, he hooked up with other students and actors who were going to Ostrava to persuade the miners to support the Velvet Revolution. On the way back, his car crashed on a frozen road. Since then, Potměšil has been paralysed from the waist down and confined to a wheelchair for the rest of his life.

He is currently a prominent member of the Kašpar theatre company that performes in the Divadlo v Celetné, Prague. He performed major characters in several plays. The most notable ones include Charlie Gordon in Flowers for Algernon (more than ten years on the repertoire), the title role in Richard III (received Alfréd Radok Award for best actor), Jesus in Mitterer's Trouble in the House of God, or Polonius in Hamlet. In Lyra Pragensis, he performed Henri Toulouse-Lautrec in Pavlík's Beauty from Moulin Rouge, Fletcher in a scenic reading of Bach's Jonathan Livingston Seagull, and Dickie in Running from Safety of the same author.
