Llandovery railway station serves the market town of Llandovery, Carmarthenshire, Wales. The station is on the Heart of Wales Line, 29 miles 24 chains (47.2 km) from Llandeilo Junction, near Llanelli, and is located between Llanwrda and Cynghordy. All trains are operated by Transport for Wales, who also manage the station.

It was opened by the independent Vale of Towy Railway company on 1 April 1858 as the terminus of a branch from Llandeilo, although the VoTR was soon leased by the Llanelly Railway, which had built the route northwards from Llanelli in stages since 1833. The Llanelly company in turn soon became part of the GWR. The LNWR's Central Wales Extension Railway arrived from the north a decade later to complete the through route between Craven Arms and Swansea, wafter the completion of the Cynghordy viaduct.

The station sits at the bottom of an 8+1⁄2 miles (13.7 km) descent from the line's southern summit at Sugar Loaf tunnel and, until August 1964, a locomotive shed was in operation here to house the engines used for assisting northbound trains (the ruling gradient on this section being 1 in 60).

There is a passing loop and level crossing (of the A40 road) at the station, although the token instruments for the single line and crossing barriers are both operated by the train crew under the supervision of the signaller at Pantyffynnon. The loop had been temporarily decommissioned between 2008 & 2010, but is in use again after the automatic point machines were renewed in June 2010.

Refurbished station buildings were opened by Prince Charles in June 2011, having closed in 1992.

The station was shortlisted for the Best Station (Small) at the 2019 National Rail Awards.

The station is unstaffed and has no ticket machine, so all tickets need to be purchased prior to travel or on board the train. There are shelters, CIS screens and customer help points on each platform. Step-free access is provided to both platforms.

A local volunteer group runs a cafe and gallery in the main station building.
