Briton Hadden (Feb. 18, 1898–Feb. 27, 1929) was the co-founder of Time Magazine with his Yale classmate Henry Luce.

Hadden got his start in newspaper writing at the Hotchkiss Record. After "heeling" the Yale Daily News, he was elected to its staff and later served as the paper's chairman twice, from 1917–1918 and from 1919–1920. Luce was the News' managing editor both times.

After graduation, Hadden did some newspaper work but found the current options unsatisfying. In 1923, he co-founded Time Magazine. Luce and he served alernating years as the company's president. Luce went on to grow that first magazine into the Time-Life empire, but in December 1928, Hadden became ill and eventually died of a throat infection caused by influenza.

After his death, Luce donated funds towards the construction of a building at 202 York Street in New Haven, CT that would eventually become the Yale Daily News' new home. The office is today called the Briton Hadden Memorial Building.
