New York Social Diary is a website that publishes photographs of "the rich and powerful" socialites and a social calendar of events that they might attend. It is maintained by David Patrick Columbia, who founded it in 2000.
The Diary originated in 1993 as a monthly column in Quest magazine. The column had a similar focus to the present website.
Many people are in the social diary.
Chase Coleman III of old money and notoriously publicity-shy, has refused to be photographed for any publication since his 2005 wedding photographed by the New York Social Diary.
