Sileby is a former industrial village and civil parish in the Soar Valley in Leicestershire, between Leicester and Loughborough. Nearby villages include Barrow upon Soar, Mountsorrel, Ratcliffe-on-the-Wreake, Seagrave and Cossington. The population of the civil parish at the 2011 census was 7,835.

The origins of the village date back to around 840 AD when the area was settled by the Danes - Leicestershire forming part of the Danelaw along with other counties in the vicinity. The name Sileby may in fact come from the Danish name 'Sighulf'.

The village lies at the bottom of an ancient valley created by the nearby River Soar, meaning that surrounding farmland is particularly prone to flooding during persistent or heavy rain.

Traditionally, Sileby was split into two wards, separated by the brook that flows through the middle of the village. These are St Mary's to the north and St Gregory's to the south. Recently however, due to Boundary Commission changes, a third ward of Barrow West was added albeit as an arbitrary boundary essentially for electoral purposes. This division was strongly resented at the time owing to local rivalries and the idea of a portion of the village being annexed was not popular. In practice however this division is largely ignored. Even the idea of the two traditional wards is becoming somewhat lost as the village grows and new people move in unaware of the significance of the historical division.

One of Sileby's most distinguishing features is the Anglican church of St. Mary founded around 1152. It is a Grade II* listed building, and only 4% of listed buildings in the country are Grade II* status, which means it is of very significant interest. The Gothic tower now houses a fine ring of 10 bells, which attract ringers from far and wide. The church has an active congregation and hosts Ladies Fellowship on Tuesday afternoons and Squeals for Tots on a Thursday morning. There is an active youth ministry and children's work led by Leonie Poole the Children and Families Worker. The church is open from 2pm on a Wednesday for coffee. The Rector is the Revd Duncan Beet. The service on a Sunday is at 11.00am and there are both children and youth groups in the state of the art St Mary's Centre. There is also a crèche in the main church building.

Sileby Primitive Methodist Church was built in 1866 to the designs of James Kerridge. Sileby Wesleyan Methodist Church on High Street was built in 1884.

In more recent history Sileby was very much an industrial place. Like most towns/villages in the local area it had several hosiery and shoe factories until as recently as the 1980s, as well as a wallpaper manufacturer and several engineering companies. Nearly all of these have now disappeared and most of the factory premises have long since been demolished and replaced by new housing estates, essentially making it a modern commuter town for people who work throughout the East Midlands and even beyond with easy access to London and the North.
