Longburn (or Karere) is a rural settlement just outside of Palmerston North in the Manawatu-Wanganui 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.
Longburn is significant in railway history, as it was the northern terminus of New Zealand's most prominent private railway, the Wellington and Manawatu Railway Company (WMR). Its line between Longburn and Wellington was completed in 1886 and at Longburn, passengers and goods transferred between the WMR and the New Zealand Railways Department (NZR) network. On 8 December 1908, the WMR was absorbed into the NZR and Longburn lost its significant interchange status. The line through Longburn is now part of the North Island Main Trunk Railway.
