OK, Article III, Section 2, Clause 22:

In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make.

The legal definition of 'jurisdiction' is the authority to interpret and apply the law within a particular geographic area and/or over certain types of legal cases.
