is a football club that represents the town of Newark-on-Trent, Nottinghamshire and were based at the Lowfields Ground, Hawton Lane, Balderton for over 100 years, (1901 - 2021).

No records survive from those early days, but it is known that in 1935 the club, now renamed Worthington Simpson, entered the Nottingham Spartan League.

Name changes followed in the late ‘90s, first to IDP and then to Newark Flowserve, and in 2004 the club’s name was entered into the first level of the FA’s national pyramid by joining the Central Midlands League Premier Division.

Another successful campaign followed a year later when the team finished runners-up and clinched their place in the NSL Premier Division, taking the club back to step seven football.

The club played their home games for the season 2021/22 at Basford Utd's Greenwich Ave ground.

In May 2023 the club won the Notts Senior Cup for the first time in their history by beating Carlton Town 3-2 in the final played at Eastwood.
