The number 69 simply refers to the integer that follows 68 and precedes 70 in the natural number sequence. In mathematics, it is an odd composite number. It can be factored as 3×23. Additionally, it is the 22nd semi-prime number and a Ulam number. Beyond its mathematical properties, the number appears in various contexts; for example, it is the international calling code for Thailand.

The number 69 is also widely known as a term for a sexual position in which two people simultaneously perform oral sex on one another. The term derives its name from the visual resemblance of the position to the number's digits: one person's head is near the other's genitals, and vice-versa, creating a symmetrical, often yin-yang-like arrangement. This meaning is common in colloquial language and popular culture.
