List of oil spills
This is a reverse-chronological list of oil spills that have occurred throughout the world and spill that are currently ongoing. Quantities are measured in tonnes of crude oil with one tonne roughly equal to 308 US gallons, 256 Imperial gallons, 7.33 barrels, or 1165 litres. This calculation uses a median value of 0.858 for the specific gravity of light crude oil; actual values can range from 0.816 to 0.893, so the amounts shown below are inexact. They are also estimates, because the actual volume of an oil spill is difficult to measure exactly.
Confirmed spills
| Spill or vessel | Location | Dates | Tonnes | Tonnes | Owner | Ref |
| 2025 Johor Strait palm oil spill |  MalaysiaInvestigation underwayNote: The "flow rate" column applies to leaking wells, pipelines, etc., and is often used to estimate the total amount of oil spilled. The "full cargo" column applies to vessels, vehicles, etc., and represents the maximum amount of oil that could be spilled. The "spilled" columns indicate the total amount of oil that has been released to the environment so far, and should be based on official estimates found in referenced sources whenever possible. When official estimates vary, use the "min tonnes" and "max tonnes" columns to show the range of estimates in metric tonnes.Oil spills in the United StatesThis graphic is limited to oil spills that occurred between 1969 and 2015 and that affected US waters. Unlike the units of tonnes used on the rest of this page, the graphic's numbers are presented in millions of US gallons, where 1 MG is roughly equal to 3,250 tonnes of crude oil. |
