Basin Reserve is a cricket ground in Wellington, New Zealand used for staging test, first-class and one-day cricket.

The ground is located two kilometres south of what is now the CBD, at the foot of Mount Victoria. It is adjacent to present-day Government House, Wellington College and St Mark's Church and School.

The area that is now Basin Reserve was originally a lake (known as the Basin Lake), and there were plans to connect it to the sea by a canal to make it an alternative inner city harbour, but an earthquake in 1855 uplifted the area nearly 1.8 m and turned the lake into a swamp. The swamp was drained and by 1866 Basin Reserve became Wellington's official cricket ground.

The first test match played at the ground was between New Zealand and England, beginning January 24, 1930 and at least one test match has been played at the ground each season since. One-day international cricket has also been played at the Basin; regularly until 1999, after which it moved to the larger crowd capacity Westpac Stadium on the other side of Wellington city, and in what may be a one-off occasion, returns during the Australian Tour in 2005 following a decision that the pitch at Hamilton's Westpac Park was unfit for cricket.

In addition to cricket, other sports have also used the Basin, including rugby (some historians claim that the first inter-school rugby match in the world was held at the Basin between Nelson College and Wellington College in 1870) and exhibition Australian rules football matches.

One of the incidental quirks of the Basin is that it acts as the largest traffic island in the southern hemisphere.
