In accordance with the FBI definition, statutory rape is characterized as non-forcible sexual intercourse with a person who is younger than the statutory age of consent. There are only a few states in the nation that actually call it "Statutory Rape" within the written law. In Oregon, this crime could fall under a few different statutes depending on the age of the victim. 163.415 Sex abuse in the third degree describes the actual "Age of consent" to have consensual sex in Oregon. This, along with 2nd and 3rd degree rape, would be considered "Statutory Rape" laws.

163.415 Sexual abuse in the third degree. (1) A person commits the crime of sexual abuse in the third degree if the person subjects another person to sexual contact and:
(a) The victim does not consent to the sexual contact; or
(b) The victim is incapable of consent by reason of being under 18 years of age.
(2) Sexual abuse in the third degree is a Class A misdemeanor.
