After a break during the war years the club was re-founded in 1954 and changed its name to Henley RFC in 1963.

Henley's fortunes stood still until Clive Woodward, England's future World Cup winning manager, became the 1st XV coach in 1990.

His introduction of the "flat ball" philosophy was a pioneering event for British rugby and brought promotion in 1992. Henley gained a further promotion in 1994 to the National Leagues and, after Woodward departed to coach London Irish, Henley continued to play fluid rugby and two further promotions ensued (in the 1997–98 and 1998–99 seasons), landing the club in what is now National Division One.

Also in 1999, Henley enjoyed a record run in the Tetley's Bitter Cup, defeating the Premier 1 club Bedford in the fourth round before bowing out to Gloucester at Kingsholm.

On 4 May 2013, Henley Hawks beat Worthing 55–27 to secure a place in National Division One for the 2013–14 season.
