Roger Davis (born 15 January 1946) is a former county cricketer. He became, briefly, headline news in 1971, when a ball hit him on the side of the head while he was fielding in the dangerous "short leg" position, causing his heart to stop.

He was born in Cardiff, Wales, and first played for Glamorgan in 1964 as an all-rounder. In 1968, he came close to preventing the record-breaking 36 runs in one over, scored by Gary Sobers in a match at Swansea. In 1969, he helped Glamorgan to their county championship victory. Two years later, in a match against Warwickshire at Cardiff, the accident occurred which nearly resulted in Davis's death. The kiss of life was administered on the field by a doctor who happened to be in the crowd. As an indirect result of the incident, fielders and batsmen in first-class cricket began wearing protective headgear. After making a full recovery, Davis continued to play for Glamorgan until 1976.
