Rowby-John Rodriguez (born 27 March 1994) is an Austrian professional darts player currently playing in events of the Professional Darts Corporation (PDC).
In 2010, as a 16-year-old, Rodriguez won the Austrian National Championship by beating Franz Thaler 5–0 in the final.
At the second event of Q School in January 2014 he stood one win away from joining the PDC but lost 5–3 to Gerwyn Price. However, after all four events had been played Rodriguez had done enough to finish ninth on the Q School Order of Merit and earn a two-year tour card. His first PDC major was the UK Open where he was knocked out 5–1 by Tony Randall in the first round.
