Ballylanders (Irish: Baile an Londraigh) is a village in south County Limerick, Ireland. It is 37 km (23 mi) south of Limerick and 13 km (8 mi) north of Mitchelstown, on the R513 road. The 2016 census recorded a population of 308 people. The village is in a townland and civil parish of the same name.

Historically the name translates as "de Londra's town" and is most likely of Norman origin and referring to a popular Anglo-Norman derived family surname of "Landers" or alternatively "de Londra" can give its translation as "Town of the Londoner".

There is a holy well close to the village which is the focal point of the Pattern day, held annually on 15 August, this is one of the major such fair days in the locality. In 2011 The Wolfe Tones performed in the marquee during the pattern festival.

The present-day Catholic parish church is of a modern circular design. The first church in the village was a Church of Ireland church, dated to the 19th century, is still in existence today as a private dwelling house. The arches of the church are still visible from the inside and are preserved for aesthetic value.

The former Church of Ireland building, built in 1861, was designed by Welland and Gillespie. Its entry in the National Inventory of Architectural Heritage describes it as a "landmark building within Ballylanders" and as having "some unusual architectural features including crests of the Earls of Kingston".

Griston Bog, on the west side of the village, is a nature reserve and bird sanctuary which is home to birds, insects and plants. The 2023-2028 conservation plan for the site notes that this is a lowland raised bog. The habitats on this nature reserve include cutover bog regenerated as marsh, raised bog, wet grassland, artificial pond, reed and large sedge swamps, drainage ditches, wet pedunculate oak-ash woodland and conifer plantation. The site does not have any protected site status. The raised bog reserve and education centre at the site is managed by Ballyhoura Heritage and Environment.

Rare and/or indicator plant and animal species occurring at the site include the Common frog (Rana temporaria), Meadow pipit (Anthus pratensis), Bog moss (Sphagnum spp), lichen (Cladonia spp.), Sundew (Drosera anglica) and Common lizard (Lacerta vivipara). Griston Bog is of ornithological significance for a range of bird species, such as the Hen Harrier (Circus cyaneus) and Merlin (Falco columbarius).
