Dennis Taylor (born Denis Taylor, 19 January 1949 in Coalisland, County Tyrone, Northern Ireland) is a retired snooker player, and current BBC snooker commentator. Winner of two ranking events, he is best known for winning the 1985 World Championship, beating World number one Steve Davis on the final black in one of the sport's most memorable finals. He also won the Grand Prix in 1984 and the Masters in 1987. Taylor is also well known for his sense of humour and his trademark oversized spectacles.

Taylor turned professional in 1972 and made his world championship debut in 1973, narrowly losing to Cliff Thorburn in the first round. After world semi-final losses in 1975 and 1977, Taylor reached his first major final – the World Championship – in 1979, but lost 24–16 to debutant Terry Griffiths.

Having reached the semi final of the World Championships in 1984, losing to Steve Davis, Taylor was playing very well as he began the 1984–85 season. In September, however, he was devastated by the sudden death of his mother, which caused him to withdraw from the Jameson International. His first ranking event win came later in 1984, when he won the Rothmans Grand Prix by beating Cliff Thorburn 10–2 in the final.
