Yes, it this simple:

A natural-born citizen refers to someone who was a U.S. citizen at birth, and did not need to go through a naturalization proceeding later in life.

Article II, Section 1 of the Constitution explicitly states that "no Person except a natural born Citizen […] shall be eligible to the Office of President," among other age and residency requirements.
