余暇（英语：Leisure），又称宽暇、空闲、闲暇、休闲、自由时间（free time），意指花费在基本维生活动，如吃饭、排泄、睡眠等，以及花费在工作、家务、企业、商业活动及教育之外的时间。对于余暇的态度，随着文化与生活型态不同，在各个地区有极大的差异。

余暇与工作之间的分界，可能不太明显，特别是针对某些需要长期投入的工作。在余暇时进行的活动，通常称为休闲或消遣。将大部份时间投入工作，以致于没有余暇进行休闲，这种人通常被称为工作狂。对于余暇活动的研究，称为休闲研究（Leisure studies）。

Leisure has been defined as a quality of experience or as free time.

Free time is time spent away from business, work, job hunting, domestic chores and education. It also excludes time spent on necessary activities such as eating and sleeping. From a research perspective, this approach has the advantages of being quantifiable and comparable over time and place. Leisure as experience usually emphasizes dimensions of perceived freedom and choice. It is done for "its own sake", for the quality of experience and involvement. Other classic definitions include Thorsten Veblen's (1899) of "nonproductive consumption of time." Different disciplines have definitions reflecting their common issues: for example, sociology on social forces and contexts and psychology as mental and emotional states and conditions.
