Whangamarino was a flag station on the North Island Main Trunk line, in the Waikato District of New Zealand, 49 mi (79 km) south of Auckland. It was 598.24 km (371.73 mi) north of Wellington, 6.19 km (3.85 mi) south of Amokura, 6.72 km (4.18 mi) north of Te Kauwhata and 7 m (23 ft) above sea level.

The station opened on 13 August 1877. The early service averaged about 13 mph (21 km/h), taking some 4hrs to Auckland.

Track doubling to ease congestion was authorised in 1914, but work was delayed by the war and the line remains single. A scheme to use spoil from the Auckland City Rail Link to double the track has been considered.

Three passengers in a sleeping car died in May 1914, when an express from Wellington passed a broken signal in fog and crashed into a goods train. A porter was charged with manslaughter, but acquitted.
