The Sydney Morning Herald (SMH) is a daily compact newspaper published by Fairfax Media in Sydney. Founded in 1831 as the Sydney Herald, the SMH is the oldest continuously published newspaper in Australia. The newspaper is published six days a week. The newspaper's Sunday counterpart, The Sun-Herald, is published in tabloid format. It is available at outlets in Sydney, regional New South Wales, Canberra and South East Queensland (Brisbane, Gold Coast and Sunshine Coast).

Three employees of the now-defunct Sydney Gazette, Ward Stephens, Frederick Stokes and William McGarvie, founded The Sydney Herald in 1831. The four-page weekly had a print run of 750. In 1840, the newspaper began to publish daily. In 1841, an Englishman named John Fairfax purchased the operation, renaming it The Sydney Morning Herald the following year. Fairfax, whose family were to control the newspaper for almost 150 years, based his editorial policies "upon principles of candour, honesty and honour. We have no wish to mislead; no interest to gratify by unsparing abuse or indiscriminate approbation."

The SMH was late to the trend of printing news rather than just advertising on the front page, doing so from 15 April 1944. Of the country's metropolitan dailies, only The West Australian was later in making the switch. In 1949, the newspaper launched a Sunday edition, The Sunday Herald. Four years later, this was merged with the newly acquired Sun newspaper to create The Sun-Herald, which continues to this day.

In 1995, the company launched smh.com.au, the newspaper's web edition. The site has since grown to include interactive and multimedia features beyond the content in the print edition. Around the same time, the organisation moved from Jones Street to new offices at Darling Park and built a new printing press at Chullora, in the city's west. The SMH has since moved with other Sydney Fairfax divisions to a building at Darling Island.
