John O'Meara (1856 – 3 July 1904) was a Liberal Party Member of Parliament in New Zealand.

[2] When Thomas Fergus retired from the Wakatipu electorate prior to the 1893 election, O'Meara was one of three candidates for the position; William Fraser won the election, and O'Meara came a distant second but ahead of William Larnach.

[2][3] He was still relatively unknown in the Pahiatua electorate when he stood in the 1896 general election, and to the surprise of many, he defeated Robert Manisty and William Wilson McCardle.

[5] In 1903 he was elected as the Liberal Party's senior whip in which role he was to serve until his death.

Returning home from a bike ride, he had just passed his housekeeper when she heard him crash onto the gravel driveway; he was dead before a doctor arrived 15 minutes later.
