Notts, Lincs & Derbyshire 3 was a tier 11 English Rugby Union league with teams from Nottinghamshire, Lincolnshire and Derbyshire taking part. Promoted teams moved up to Notts, Lincs & Derbyshire 2 and since the cancellation of Notts, Lincs & Derbyshire 4 at the end of the 1995–96 season there was no relegation. At the end of the 1999–00 campaign the Notts, Lincs & Derbyshire leagues were merged with the Leicestershire leagues. This meant that Notts, Lincs & Lincolnshire 3 was cancelled after 13 seasons and all teams transferred into the new Notts, Lincs & Derbyshire/Leicestershire leagues.
