Blaby is a village in the Blaby District in central Leicestershire, England, some five miles south of Leicester city centre. It has population of around 6,240 (2001 figures), falling slightly to 6,194 at the 2011 census, and its proximity to the city causes it to form part of the Leicester Urban Area.

Its name probably came Old Norse Blábýr = "farmstead or village belonging to a man named Blár" (where the -r is a case ending). There seems to have been a dense patch of Viking settlement in Leicestershire, although some records in the Blaby Library indicate the origin of the village's name was from the first vicar. Twinned with the village of Villers-sous-Saint-Leu in France.

While there are few buildings of outstanding historical or architectural interest, old Blaby is a conservation area. It contains some ancient and picturesque dwellings and has a charming 'olde worlde' feel. Old Blaby also contains The Baker's Arms, a thatched public house that dates back to 1484. The other public houses to be found in Blaby are The Fox & Tiger, The Bulls Head and The Black Horse. The Tom Thumb has been sold from Everards brewery and had planning permission granted to build 10 dwellings in its place. The Egyptian Queen has now been demolished. One of the two old schools in Blaby is Park (Parkwood) House; the other is in the surrounding area near the parish church.

To the south of the Bakers Arms stands Bouskell Park, with a 19th-century ice house and car parking. There are also Northfield Park, used for football, cricket, fetes and fairs, and Oakfield Park, located off Hospital Lane.

The following is an overview of features dating back to 1950s Blaby:

• Shoults' Tomato Farm was among the main horticultural businesses (outside of local farmers), but by 1950 had become a wasteland, later to be developed for residential housing.
• Farmer Rest (whose Farm was situated at the top end of Church Street before its junction with Wigston Road and Mill Lane) and Farmer Bert Attfield (whose land was mainly within Whetstone and Whetstone Gorse, bordering with Hillview Nurseries on the Lutterworth Road, Blaby) were two of the main conventional farmers.
• Blaby Rose Gardens was a celebrated rose grower and developer, owned and run by a Dutch specialist. Outside of the small industries of hosiery and boots and shoes, with factories (e.g. Griffin & Gamble) in Blaby Village, the rose gardens were an important employer, but also relied on seasonal workers in the form of university students.
• Hillview Nurseries was another employer of casual workers. Kenneth Morey founded this market garden, located opposite Blaby Rose Gardens on the Lutterworth Road. A smallholding by any standards, it also relied on university students for pea-picking and other seasonal crops.
