Millbrook railway station is a small station in the Millbrook area of Southampton, England. It is served mainly by the Salisbury to Romsey stopping service. This service runs once per hour in each direction.

It is 80 miles 11 chains (129.0 km) down the line from London Waterloo. The station is managed by South Western Railway. The platforms face the slow lines only, there are no platforms for the fast lines.

Millbrook Freightliner Terminal is located next to the station on the up side. A car terminal and rail access to Southampton's Western Docks can be seen from the down side of the station.

In summer 2021, works were undertaken to improve the footbridge that connects the island platform with Millbrook Road West. Southampton city council was able to use the rebuild to remove two steps at the northern end where the bridge joins Foundry Lane and replace them with a ramp. Limited space and a large volume of underground utilities meant Network rail left the southern end at the station steps only.

The typical off-peak service in trains per hour is:

• 1 tph to Salisbury via Romsey
• 1 tph to Romsey via Chandler's Ford
