Siron Khurd is a village in Jakhaura block of Lalitpur district, Uttar Pradesh, India.

It is identified with the early medieval city of Sīyaḍoṇi, which was a major commercial and political centre during the 10th century under the Gurjara-Pratihāra empire.

The primary source for the medieval city is a single inscription found at Siron Khurd in the late 1800s.

[3]: 137  According to Aman Mishra, Sīyaḍoṇi's growth as a city was because of its location on an important trade route.

Mishra writes that the city's economy was primarily based on long-distance trade, and locals also engaged in rent-seeking behaviour such as charging rent on land or interest on loans.

[3]: 136–7 Various types of artisans are mentioned in the Sīyaḍoṇi inscription: potters, stonecutters, sugar boilers, oil millers, and liquor distillers.

The exact nature of this arrangement is unclear; the feudatories may have been assigned to govern the city on a temporary basis.

For example, the first donation mentioned is one where the whole town, as a corporate body, granted a field to the temple of Nārāyaṇabhattāraka.

The village had no post office or public library; there was at least some access to electricity for residential and agricultural purposes.
