Ryan Gentles (November 28, 1977) is the manager of the New York City-based band, The Strokes. Before meeting the Strokes, he was the vocalist and guitarist in two bands, Timmsie's First Time, which broke up in 1995 and The Selzers, which broke up in 2000. Matthew Romano, The Strokes' drum technician and back-up drummer, was also in both bands, playing drums. Recently Ryan has stated that being part of the Selzers "was not exactly a proud moment" for him.

Gentles met the Strokes when he was booking bands for the Mercury Lounge in New York. He was so impressed by them that he quit his job to become their manager. He is now often considered to be "the sixth Stroke". He played a starring role in their music video "The End Has No End".
