Aframax refers to a class of oil tanker of medium size, larger than Panamax and smaller than Suezmax.

Aframax tankers are in the range of 80-120 dwt. The typical drafts vary by vessel but are usually in the region of 14.5 - 15.5m. They are used for crude and product shipment. If moving product, they are often called LR2.

Aframax crude tankers are typically used in short to medium distance routes and serving ports that can not handle the larger and lower-cost per barrel Suezmax or VLCC tankers.

The name comes from an oil tanker rate system introduced by Shell called the Average Freight Rate Assessment.
