The Age is a daily newspaper in Melbourne, Australia, that has been published since 1854. Owned and published by Nine Entertainment, The Age primarily serves Victoria, but copies also sell in Tasmania, the Australian Capital Territory and border regions of South Australia and southern New South Wales. It is delivered both in print and digital formats. The newspaper shares some articles with its sister paper The Sydney Morning Herald.

The Age is considered a newspaper of record for Australia, and has variously been known for its investigative reporting, with its journalists having won dozens of Walkley Awards, Australia's most prestigious journalism prize. As of March 2020^[update], The Age had a monthly readership of 5.4 million. As of September 2024^[update], this had fallen to 4.55 million.

The Age was founded by three Melbourne businessmen: brothers John and Henry Cooke (who had arrived from New Zealand in the 1840s) and Walter Powell. The first edition appeared on 17 October 1854.

The venture was not initially a success, and in June 1856 the Cookes sold the paper to Ebenezer Syme, a Scottish-born businessman, and James McEwan, an ironmonger and founder of McEwans & Co, for £2,000 at auction. The first edition under the new owners came out on 17 June 1856. From its foundation the paper was self-consciously liberal in its politics: "aiming at a wide extension of the rights of free citizenship and a full development of representative institutions", and supporting "the removal of all restrictions upon freedom of commerce, freedom of religion and—to the utmost extent that is compatible with public morality—upon freedom of personal action".

Ebenezer Syme was elected to the Victorian Legislative Assembly shortly after buying The Age, and his brother David Syme soon came to dominate the paper, editorially and managerially. When Ebenezer died in 1860 David became editor-in-chief, a position he retained until his death in 1908, although a succession of editors did the day-to-day editorial work.

In 1882 The Age published an eight-part series written by journalist and future physician George E. Morrison, who had sailed, undercover, for the New Hebrides, while posing as crew of the brigantine slave ship, Lavinia, as it made cargo of Kanakas. By October the series was also being published in The Age's weekly companion magazine, the Leader. "A Cruise in a Queensland Slaver. By a Medical Student" was written in a tone of wonder, expressing "only the mildest criticism"; six months later, Morrison "revised his original assessment", describing details of the schooner's blackbirding operation, and sharply denouncing the slave trade in Queensland. His articles, letters to the editor, and newspaper's editorials, led to expanded government intervention.

In 1891, Syme bought out Ebenezer's heirs and the McEwans and became sole proprietor. He built up The Age into Victoria's leading newspaper. In circulation, it soon overtook its rivals The Herald and The Argus, and by 1890 it was selling 100,000 copies a day, making it one of the world's most successful newspapers.

Under Syme's control The Age exercised enormous political power in Victoria. It supported liberal politicians such as Graham Berry, George Higinbotham and George Turner, and other leading liberals such as Alfred Deakin and Charles Pearson furthered their careers as The Age journalists. Syme was originally a free trader, but converted to protectionism through his belief that Victoria needed to develop its manufacturing industries behind tariff barriers. During the 1890s The Age was a leading supporter of Australian federation and of the White Australia policy.
