Liquidation is the process in accounting by which a company is brought to an end in Canada, United Kingdom, United States, Ireland, Australia, New Zealand, Italy, and many other countries. The assets and property of the company are redistributed. Liquidation is also sometimes referred to as winding-up or dissolution, although dissolution technically refers to the last stage of liquidation. The process of liquidation also arises when customs, an authority or agency in a country responsible for collecting and safeguarding customs duties, determines the final computation or ascertainment of the duties or drawback accruing on an entry.

Liquidation may either be compulsory (sometimes referred to as a creditors' liquidation or receivership following bankruptcy, which may result in the court creating a "liquidation trust"; or sometimes a court can mandate the appointment of a liquidator e.g. wind-up order in Australia) or voluntary (sometimes referred to as a shareholders' liquidation or members' liquidation, although some voluntary liquidations are controlled by the creditors).

The term "liquidation" is also sometimes used informally to describe a company seeking to divest of some of its assets. For instance, a retail chain may wish to close some of its stores. For efficiency's sake, it will often sell these at a discount to a company specializing in real estate liquidation instead of becoming involved in an area it may lack sufficient expertise in to operate with maximum profitability. A company may also operate in a "receivership-like" state but calmly sell its assets, for example to prevent its portfolio being written off in the event of an actual compulsory liquidation.
