Standon is a village and civil parish in Hertfordshire, England. The parish includes the adjoining village of Puckeridge and Old Hall Green. The Grade I listed parish church of St Mary has Anglo-Saxon origins with much Victorian restoration of 1864-65 by H. and G. Godwin. The chancel contains the ornate tombs of the Tudor courtier Sir Ralph Sadler and his son Thomas Sadleir. The house Standon Lordship was built by Ralph Sadler on his estate at Standon, which he acquired in 1544; Standon remained in the possession of the Sadler family until 1660.

The place-name is first attested in an Anglo-Saxon charter of 944–46 AD and means "stony hill".

Standon village has many local facilities. In addition to the church, there is a village hall, two public houses, a Chinese restaurant, post office, butcher, baker, and newsagent. Villagers also make frequent use of facilities in neighbouring Puckeridge, which include a pharmacy, estate agent, petrol station, public houses, doctor's surgery and primary schools (including St Thomas of Canterbury, a Roman Catholic primary school).

Arthur Martin-Leake, one of only three men to be awarded the Victoria Cross twice, was born in the village.
