日常生活活动（英语：Activity of daily livings）是用于医疗照护的用语，特别用在年长者的照顾上。

日常生活活动是指在日常生活普遍会进行的活动，包含表现自我照顾（例如自己进食、沐浴、更衣、整理仪容）、工作、家庭杂务及休闲娱乐的任何日常活动。许多全国性的调查收集了美国人口日常生活动状态的数据。

健康专业通常以是否能表现日常生活活动，来测量个人的功能状态。此测量常用于年长者的评估、精神病患、慢性病患者及其他，以评估何种健康照顾可以符合个人所需。 评估工具有数种，例如Katz ADL scale和Lawton IADL scale。

Activities of daily living (ADLs or ADL) is a term used in healthcare to refer to people's daily self care activities. The concept of ADLs was originally proposed in the 1950s by Sidney Katz and his team at the Benjamin Rose Hospital in Cleveland, OH and has been added to and refined by a variety of researchers since that time. Health professionals often use a person's ability or inability to perform ADLs as a measurement of their functional status, particularly in regard to people post injury, with disabilities and the elderly. Younger children often require help from adults to perform ADLs, as they have not yet developed the skills necessary to perform them independently.
