Daniel O'Connell (II) (1849 – 23 January 1899) was a poet, actor, writer and journalist in San Francisco, California, and a co-founder of the Bohemian Club. He was the grand-nephew of Daniel O'Connell (1775–1847), the famed Irish orator and politician.

The Bohemian Club is a private club with two locations: a city clubhouse in the Nob Hill district of San Francisco, California, and the Bohemian Grove, a retreat north of the city in Sonoma County. Founded in 1872 from a regular meeting of journalists, artists, and musicians, it soon began to accept businessmen and entrepreneurs as permanent members, as well as offering temporary membership to university presidents and military commanders who were serving in the San Francisco Bay Area. Today, the club has a membership of many local and global leaders, ranging from artists and musicians to businessmen. Membership is restricted to men only.
