The Lethbridge Herald is a Canadian English-language newspaper published six days a week in Lethbridge, Alberta. It is owned by Postmedia Network.

The Herald has been in publication since October 1903. It is the descendant of the Lethbridge Bulletin, which was founded in 1892. The Bulletin merged with the Lethbridge Daily News in 1903 to form the Herald. The publication was initially daily, except for Sundays. The Saturday edition was added in 1919, and the Sunday edition in 1966.

The Herald is one of four Postmedia newspapers serving southern Alberta, including the Calgary Herald, the Medicine Hat News, and the Red Deer Advocate.

In 2017, Postmedia acquired Sun Media's English-language newspapers in Quebec. On August 27, 2018, Postmedia announced that it would acquire Torstar's English-language daily and community newspapers in Ontario. The sale will require Canadian Radio-television and Telecommunications Commission (CRTC) approval. The purchase was completed on October 26, 2018.
