A sinecure ( or ; from the Latin sine, 'without', and cura, 'care') is an office, carrying a salary or otherwise generating income, that requires or involves little or no responsibility, labour, or active service. The term originated in the medieval church, where it signified a post without any responsibility for the "cure [care] of souls", the regular liturgical and pastoral functions of a cleric, but came to be applied to any post, secular or ecclesiastical, that involved little or no actual work. Sinecures have historically provided a potent tool for governments or monarchs to distribute patronage, while recipients are able to store up titles and easy salaries.

A sinecure can also be given to an individual whose primary job is in another office, but requires a sinecure title to perform that job. For example, the Government House Leader in Canada is often given a sinecure ministry position so that they may become a member of the Cabinet. Similar examples are the Lord Keeper of the Privy Seal and the Chancellor of the Duchy of Lancaster in the British cabinet. The minister without portfolio is a frequent example of this sinecure, often employed to give cabinet-level positions to enough members of all partners in a coalition government. Other sinecures operate as legal fictions, such as the British office of Crown Steward and Bailiff of the Chiltern Hundreds, used as a legal excuse for resigning from Parliament.
