The Orlando Sentinel is the primary newspaper of Orlando, Florida, and the Central Florida region, in the United States. It was founded in 1876 and is currently owned by Tribune Publishing Company.

The Orlando Sentinel is owned by parent company, Tribune Publishing. This company was acquired by Alden Global Capital, which operates its media properties through Digital First Media, in May 2021.^{[4][5][6][7][8]}

The newspaper's website utilizes geo-blocking, making it inaccessible from European countries.^[9]

The Sentinel's predecessors date to 1876, when the Orange County Reporter was first published. The Reporter became a daily newspaper in 1905, and merged with the Orlando Evening Star in 1906. Another Orlando paper, the South Florida Sentinel, started publishing as a morning daily in 1913. Then known as the Morning Sentinel, it bought the Reporter-Star in 1931, when Martin Andersen came to Orlando to manage both papers. Andersen eventually bought both papers outright in 1945, selling them to the Tribune Company of Chicago in 1965.^[10]

In 1973, the two publications merged into the daily Sentinel Star. Tribune appointed Charles T. Brumback as president in 1976.^[10] Harold "Tip" Lifvendahl was named president and publisher in 1981.^[11] The newspaper was renamed the Orlando Sentinel in 1982. John Puerner succeeded Lifvendahl in 1993,^[12] who was replaced by Kathleen M. Waltz in 2000.^[13] In that same year the sentinel gained seven sister newspapers as Tribune Co. announces its merger with Times Mirror, adding the Los Angeles Times, Newsday, the Baltimore Sun, the Hartford Courant and three others to the Tribune Publishing operation.^[14] Waltz announced her resignation in February 2008. Howard Greenberg, already publisher of fellow Tribune newspaper the Sun-Sentinel of Fort Lauderdale, was named publisher of both papers after Waltz left.^[15]

In 2008, the Tribune Company called for a redesign of the Sentinel. The new layout, which debuted in June 2008, was formatted to appeal to busy readers, though like all of the redesigns in Tribune's Sam Zell ownership era, was reeled back into a more traditional design with appealing elements kept after reader criticism.^[16][17]

In 2018, the Orlando Sentinel and its corporate siblings began blocking access to Internet users in the European Union because their websites lacked compliance with the EU's General Data Protection Regulation act.^{[18][19][20][9]}

According to one listing, some of the Sentinel's predecessors are:^[21]

• Orlando Reporter: 1892–1903? (merged with Evening Star to form Evening Reporter-Star)
• Evening Star: January–December 1903? (merged with Orlando Reporter to form Evening Reporter-Star)
• Evening Reporter-Star: 1904?–March 1947 (continues Orlando Reporter and Evening Star; continued by Orlando Evening Star)
• Orlando Evening Star: April 1947 – 1973 (continues Evening Reporter-Star; merged with Orlando Morning Sentinel to form the Orlando Sentinel-Star)

Editorially, the Sentinel tilted conservative. From 1952 to 2004, it endorsed Republicans in every election save for Lyndon Johnson in 1964.^[22] However, it has endorsed Democratic candidates for president in four of the last five presidential elections: John Kerry in 2004, Barack Obama in 2008,^[23] Hillary Clinton in 2016,^[24] and Joe Biden in 2020.^[25]

In June 2019, the day of President Donald Trump's re-election campaign launch rally in Orlando, the Sentinel made national news when the editorial board published a piece saying it would not endorse the president, among their reasons, "the chaos, the division, the schoolyard insults, the self-aggrandizement, the corruption, and especially the lies."^{[22][26][27][28]} It ultimately endorsed Biden, saying that he was "many things that Trump is not now and never will be."^[25]
