The 29th New Zealand Parliament was a term of the Parliament of New Zealand. It opened in 1950, following the 1949 general election. It was dissolved in 1951 in preparation for the 1951 general election. The governing Labour Party had been defeated in the election by the National Party. This marked the end of the First Labour government and the beginning of the First National government.

The New Zealand Parliament is the unicameral legislature of New Zealand, consisting of the Sovereign (King-in-Parliament) and the New Zealand House of Representatives. The King is usually represented by his governor-general. Before 1951, there was an upper chamber, the New Zealand Legislative Council. The New Zealand Parliament was established in 1854 and is one of the oldest continuously functioning legislatures in the world. It has met in Wellington, the capital of New Zealand, since 1865.
