The Wellington and Manawatu Railway Company was a private railway company that built, owned and operated the Wellington-Manawatu railway line between Thorndon in Wellington, the capital of New Zealand, and Longburn, near Palmerston North in the Manawatu, between 1881 and 1908, when it was acquired by the New Zealand Government Railways. Its successful operation in private ownership was unusual for early railways in New Zealand.

Longburn is a rural settlement just outside Palmerston North in the Manawatū-Whanganui area of New Zealand. Made up of large dairy processing plants Longburn is often mistaken to be a small township and not seen as a large satellite town of Palmerston North. The township is home to both Longburn School and Longburn Adventist College.
