The Wairarapa Line is a New Zealand interurban commuter rail service along the Wairarapa Line between Masterton, the largest town in the Wairarapa, and Wellington. It is operated by Wellington suburban operator Transdev (with KiwiRail sub-contracted to operate the locomotives) under contract from the Greater Wellington Regional Council. It is a diesel-hauled carriage service, introduced by the New Zealand Railways Department in 1964 after passenger demand between Masterton to Wellington exceeded the capacity of the diesel railcars then used.

The 91-kilometre (57 mi) service operates five times daily in each direction Monday to Friday, three peak and two off-peak, with an additional service each way on Friday nights and two services each way on weekends and public holidays. It stops at all stations from Masterton to Upper Hutt, then runs express along the Hutt Valley Line to Wellington, stopping only at Waterloo and Petone stations.

While most regional passenger trains in New Zealand have been withdrawn (apart from the Capital Connection commuter service to Palmerston North and the Te Huia between Auckland and Hamilton), the Wairarapa Connection service continues due to the Wairarapa's proximity to Wellington and the advantage of the 8.8 km Remutaka Tunnel through the Remutaka Ranges compared to the narrow and winding Remutaka Hill Road over them. In the year to 30 June 2013, the service's ridership was 705,000, down slightly from 719,000 in the 2011/12-year. 780,000 used the train in 2019.
