River Road is a residential suburb of Hamilton, sited on the eastern bank of the Waikato River. The namesake road runs from Claudelands Bridge north to Pukete Bridge and beyond, to Ngāruawāhia, but the main part of the suburb is between Boundary Road and Donny Park. Properties close to the river are much more expensive than those further away. Most of River Road was shown on an 1865 map, though it was some years later before it was built and, by 1866, only one bridge had been built.

A walking path runs along the river bank, but it does not cover the entire length of the area.

Miropiko statistical area, which corresponds to River Road, covers 2.08 km (0.80 sq mi) and had an estimated population of 3,390 as of June 2024, with a population density of 1,630 people per km.
