Incumbent George Alexander was re-elected for a second full term against Job Harriman.

Municipal elections in California, including Mayor of Los Angeles, are officially nonpartisan; candidates' party affiliations do not appear on the ballot.

[1] Incumbent George Alexander had been elected in March 1909 and was now seeking a second term.

He was challenged by Job Harriman, an ordained minister and Socialist, William C. Mushet, who ran in the previous election, Miles S. Gregory, a fellow Republican and Councilmember, and James O. Becker, a Socialist Labor candidate.

"[3] However, in the general election, Alexander won due to Harriman's association with James and John McNamara, who he was one of the lawyers for during their trial for the Los Angeles Times bombing.
