Floyd Alfred MacFarland (July 9, 1878 – April 17, 1915) was an American track cyclist and pioneer of six-day racing.

MacFarland competed mainly in sprint events early in his career, having won the national championships in this discipline.

After retiring from competition, he became one of the leading race promoters and managers in the nation up until his death in 1915.

In April 1915, MacFarland was stabbed to death with a screwdriver while training at the Newark Velodrome, after being involved in a dispute with David Lantenberg, a refreshments seller who had used screws to put up a billboard by the track.

MacFarland, who was the director of the track, had forbidden this as the screws would often come loose and pose a danger to cyclists.
