Themelthorpe is a very small, rural parish in the district of Broadland, in Norfolk, England. Set in gently rolling agricultural countryside to the north‑west of Norwich and close to market villages such as Reepham and Aylsham, it comprises scattered farms, pockets of woodland and quiet lanes rather than a single built‑up centre.
The parish is noted locally for its railway legacy - the mid‑20th‑century curve that linked nearby lines remains of interest to enthusiasts and can still be traced on footpaths - and for its long‑standing agricultural economy. Social life is small‑scale and outward‑looking, with many residents relying on neighbouring villages for shops, schools and community activities.
