The Geelong Advertiser is a daily newspaper circulating in Geelong, Victoria, Australia, the Bellarine Peninsula, and surrounding areas. First published on 21 November 1840, the Geelong Advertiser is the oldest newspaper title in Victoria and the second-oldest in Australia. The newspaper is currently owned by News Corp. It was the Pacific Area Newspaper Publishers Association 2009 Newspaper of the Year (circulation 25,000 to 90,000).

The Geelong Advertiser was initially edited by James Harrison, a Scottish emigrant, who had arrived in Sydney in 1837 to set up a printing press for the English company Tegg & Co.

Moving to Melbourne in 1839, he found employment with John Pascoe Fawkner, as a compositor, and later editor, of Fawkner's Port Phillip Patriot. When Fawkner acquired a new press, Harrison offered him £30 for the original press, and started Geelong's first newspaper. The first edition of the Geelong Advertiser, which originally appeared weekly, was published on Saturday 21 November 1840, edited by 'James Harrison and printed and published for John Pascoe Fawkner (sole proprietor) by William Watkins...'

Its first editorial offered the following doggerel:

Bring forth the press!

When first that mighty shout was heard.
Truth rose in radiant light ensphered.

The Nations to address.

By November 1842 Harrison had become the sole owner of the paper. For the first seven years it was printed in demi-folio size before changing to broadsheet. In 1858 the newspaper retired the original wooden press, adopted new typography, and was printed by a mechanised steam press.^{[citation needed]}
