Child Interstate Abortion Notification Act - Amends the federal criminal code to prohibit transporting a minor child across a state line to obtain an abortion (deems such transporting to be a de facto abridgment of the right of a parent under any law in the minor’s state of residence that requires parental involvement in the minor’s abortion decision). Makes an exception for an abortion necessary to save the life of the minor.

Makes it an affirmative defense to a prosecution or civil action under this Act that a defendant: (1) reasonably believed that before the minor obtained the abortion, the required parental consent or notification or judicial authorization took place; or (2) was presented with documentation showing that a court waived parental notification requirements or authorized the minor's abortion.

Defines "abortion" to mean the use or prescription of any instrument, medicine, drug, or any other substance or device: (1) to intentionally kill the unborn child of a woman known to be pregnant; or (2) to intentionally prematurely terminate the pregnancy of a woman known to be pregnant with an intention other than to increase the probability of a live birth or of preserving the life or health of the child after live birth, or to remove a dead unborn child.

Imposes a fine and/or prison term of up to one year on a physician who performs or induces an abortion on an out-of-state minor in violation of parental notification requirements. Requires such physician to give 24-hour actual or constructive notice to a parent of the minor seeking an abortion, subject to certain exceptions.
