Steven Robert Prest (1966 – 13 May 2009) was an English professional snooker player and coach.
Prest competed on the professional snooker circuit in the 1990s before turning to full-time coaching.
His professional career spanned a total of seven seasons, bringing no success. Prest began his first season in 1991 ranked 149th in the world, which would be the highest position he would reach, and was relegated from the tour in 1997. Although he regained his place for the 1998–99 season, the highlight of Prest's career was reaching the last 64 of two ranking events - the 1991 Dubai Classic, where he lost 4–5 to Dene O'Kane, and the 1993 International Open, where he was defeated 1–5 by the veteran Eddie Charlton.
Prest worked with youngsters in his native Yorkshire and was an accredited World Snooker coach.
Prest was the manager and coach of Shaun Murphy, the 2005 World Snooker Champion.
In the early 2000s, he coached Neil Robertson of Australia, also working with Simon Bedford from Bradford. In addition to this, Prest became Ronnie O'Sullivan's long potting coach, in March 2009, but died at the end of May that year from peritonitis, aged 43.
