Ayotte v. Planned Parenthood of Northern New England, 546 U.S. 320 (2006), was a decision by the Supreme Court of the United States involving a facial challenge to New Hampshire's parental notification abortion law.

The opinion was delivered by Justice Sandra Day O'Connor, who had been significantly responsible for developing the Court's recent abortion jurisprudence.

[4] Attorney General and future U.S. senator Kelly Ayotte, who replaced Heed in 2004, appealed the case to the Supreme Court of the United States over the objections of Benson's successor, Governor John Lynch.

[5] The Court vacated the judgment of the First Circuit in a unanimous decision authored by Associate Justice Sandra Day O'Connor.

[7] The New Hampshire parental notification law was passed again in 2011 after the Republican-controlled House and Senate overrode then-Democratic governor John Lynch's veto.
