George P. McLain (August 26, 1847 – August 5, 1930) was a Civil War veteran, a covered-wagon pioneer and an advertising man who became a member of the Los Angeles, California, City Council at the turn of the 19th–20th centuries and was also on the Fire Commission in that city.

He enlisted in the Army in September 1863 and saw Civil War service in Kentucky and Tennessee with Company L, 16th Illinois Cavalry.

[1] He was recognized as a "covered wagon pioneer" who made his way west beginning in St. Joseph, Missouri, in 1866 with four yoked oxen.

[1] He was married to Guadalupie Billderain of Los Angeles; they had children George B. and Olympia (Byrd).

Other memberships were in the Sons of the Revolution, Union League Club, Los Angeles Pioneers, Odd Fellows and Independent Order of Foresters.

[1] McLain put himself forward as a candidate for the Republican nomination for sheriff at least twice—in 1892[11]—and 1898, when the Times opposed him because he permitted "the disreputable elements of the push to take a prominent part in his campaign.

[13] From the Los Angeles Times, March 20, 1887: George P. McLain owns a house on Requena Street,[14] which is rented to Rose King, a lady of easy virtue.

Constable Smith went down to enforce the law, and though he met with protestations and tears on the part of defendant, he inexorably did his duty by levying on an Arion piano.
