William Frederick L. Stanley (1872–1939) was an Irish lawyer who served as judge of the Republic of Hawaii.

[2] One major case was the window of French physician Georges Phillipe Trousseau (1833–1894).

[3] On November 1, 1897 he was appointed to be the youngest circuit court judge at the time, after Alfred Wellington Carter resigned.

[5] He had fallen out of favor with the Republican Party of Hawaii because he was not a United States citizen, but as judge presided when others were naturalized.

[1] Back in private practice, he became partner with Henry Holmes until 1915, with Wilder until 1916, by himself until 1920, and then with William Owen Smith and Warren.
