The legal age of consent for sexual activity varies by jurisdiction across Asia. The specific activity engaged in or the gender of participants can also be relevant factors. Below is a discussion of the various laws dealing with this subject. The highlighted age refers to an age at or above which an individual can engage in unfettered sexual relations with another who is also at or above that age. Other variables, such as homosexual relations or close in age exceptions, may exist, and are noted when relevant.

The unrestricted age of consent is the legal age from which one is deemed able to consent to having sex with anyone else at or above the age of consent, or the marriageable age if they must be married. The lowest unrestricted age of consent in Asia is the onset of puberty, though this is only the case in Afghanistan. The highest unrestricted age of consent is 21, though this age of consent is only the case in Bahrain and the specific instance of females receiving anal sex in Hong Kong. Disregarding these exceptions, the unrestricted ages of consent in Asia range between 13 and 18.
