Oil Mill Market is one of Port Harcourt's major commercial markets, serving the northern residential areas of the city. It functions as a general-purpose market covering fresh produce, household goods, clothing, and electronics, and is considerably less chaotic than the more famous Mile 1 and Mile 3 markets in the city centre.
The market gets its name from the palm oil processing operations that once dominated this part of Port Harcourt — a reminder that before crude oil transformed the economy, palm oil was the commodity that drove Rivers State's trade. Today the market is a practical shopping destination for residents of the Rumuokoro and Elelenwo areas, and its surrounding streets are busy with small traders and food stalls throughout the day.
