A Personal Support Worker (PSW) is a caregiver who assists people with daily personal care needs as they deal with the effects of aging, injury or illness. A PSW works under the direction of a Registered Nurse (RN) or Registered Practical Nurse (RPN).

It is important to differentiate between PSWs in health care facilities and home care. Positions in home care such as health care aides, home support workers, personal care workers and attendants (see "Similar titles") are mostly unregulated.

In the course of remaking the health care system in Canada, Personal Support Workers are reported to be in growing demand.
