Port Darwin is an electoral division of the Legislative Assembly in Australia's Northern Territory. It was first created in 1974, and is an entirely urban electorate, covering only 11 km² and taking in the Darwin central business district, as well as the suburb of Larrakeyah and part of Stuart Park. There were 5,281 people enrolled in the electorate as of August 2016.

Port Darwin has almost always been a safe seat for the Country Liberal Party, although it was one of only two seats the party did not hold in the first parliament from 1974 to 1977. It was widely considered as CLP heartland, and was their safest seat in Darwin for many years. The strength of the CLP vote in the seat was seen at the 2000 by-election caused by the resignation of controversial former Chief Minister Shane Stone, when a struggling CLP still managed to easily fend off any challenge in the seat. After the Australian Labor Party victory at the 2001 election, it became the only CLP-held seat west of Palmerston, and the only CLP seat in the capital. As a result, there were very few signs in the lead-up to the 2005 election that sitting member Sue Carter was in danger, with most commentators expecting her to win another term. However, on election day, there was a surprise significant and unprecedented swing to the ALP across the Territory. Though the result was so close that it was not known for several days after the election, Carter was ultimately defeated by Labor opponent Kerry Sacilotto by 73 votes. Sacilotto actually won just enough primary votes to take the seat without the need for preferences. She held the seat until the 2008 election, when John Elferink regained the seat for the CLP.
