Urophagia is the consumption of urine. Urine was used in several ancient cultures for various health, healing, and cosmetic purposes – practices which are still used by some today, though there is no health benefit to it. Another reason for urophagia is in attempting survival if no other potable fluid is available, although numerous credible sources (including the US Army Field Manual) advise against it. Also, some people consume urine as a sexual activity.

Some persons are sexually aroused by urolagnia, which can include the drinking of their own or other people's urine.
