The Public Health Service Outstanding Unit Commendation is a decoration of the United States Public Health Service presented to members of the United States Public Health Service Commissioned Corps.

It is the third-highest unit award of the USPHS Commissioned Corps.

The USPHS Commissioned Corps grants the Unit Commendation typically for specific actions over a relatively short and defined period of time, marked by discrete beginning and ending dates.

The determinants of the appropriate level of recognition for a USPHS unit award are the importance and significance of the unit's action or actions in furthering the mission of the USPHS Commissioned Corps and the extent to which the achievement exceeds that which is normally expected of such officers.

The USPHS Commissioned Corps grants the Unit Commendation to acknowledge significant contributions and achievements well above that normally expected in accomplishing the goals and objectives of a United States Department of Health and Human Services (HHS) operational or staff division or those of non-HHS organizations to which USPHS Commissioned Corps officers are detailed.
