Louis Napoleon Parker was an English dramatist, composer and translator. Parker wrote many plays, developing a reputation for historical works. His 1911 play Disraeli is one of his best known, written as a vehicle for the actor George Arliss who later won an Academy Award for his performance in the 1929 film adaptation, itself based on his earlier 1921 silent film version.

Disraeli is a 1929 American pre-Code historical film directed by Alfred E. Green, released by Warner Bros. Pictures, Inc., and adapted by Julien Josephson (screenplay) and De Leon Anthony (titles) from the 1911 play Disraeli by Louis N. Parker.
