Samitivej PCL (Thai: สมิติเวช), doing business as Samitivej Hospitals (Thai: โรงพยาบาลสมิติเวช), is a private hospital brand in Thailand. It operates hospitals and health centers in Bangkok and Chonburi Province.

It is owned by Bangkok Dusit Medical Services (BDMS), Thailand's largest private hospital company.

As of 2009^[update] 40% of the patients seen at Samitivej centres are non-Thai. The foreign patients, as of 2009, often refer to each hospital as "the baby hospital", and they are used by expatriates who live in countries with less developed healthcare systems; Rachel Louise Snyder, writing in Slate, described "Five-star service" as "the aphorism most often uttered in conjunction with Samitivej."

The centres offer halal food, and patients can get frequent flier miles.
