Emilie Kekāuluohi Widemann Macfarlane (October 3, 1859 – March 13, 1947) was a Native Hawaiian activist and civic organizer during the late 19th and early 20th centuries She was known for her charitable work and civic involvement in Honolulu, including women's suffrage, public health, education, and the preservation of Hawaii's historical legacy.

In 1893, shortly after the overthrow of the Hawaiian Kingdom, Macfarlane was elected the first president of Hui Aloha ʻĀina for Women, an organization formed in opposition to the deposition of Queen Liliʻuokalani and efforts to annex the islands to the United States.

Macfarlane was born on October 3, 1859, in Lihue on the island of Kauai to German immigrant and businessman Hermann A. Widemann and his Hawaiian wife, Mary Kaumana Pilahiuilani.

[12][13] Macfarlane was known for her charitable work and civic involvement in Honolulu, including women's suffrage, public health, education, and the preservation of Hawaii's historical legacy.

[14] The group was founded on March 27, 1893,[15] shortly after its male counterpart (Hui Aloha ʻĀina for Men) was formed to support deposed Queen Liliʻuokalani and oppose the overthrow and related plans to annex the islands to the United States.

[14] Macfarlane was elected the first president of the organization; her sister, Martha Widemann Berger, and Abigail Kuaihelani Campbell were vice-presidents.

[15] When US President Grover Cleveland sent James H. Blount to investigate the overthrow, both Hui Aloha ʻĀina groups drafted resolutions to restore the monarchy.

The use of the word "Queen" and the absence of Liliʻuokalani's name were the reasons for suspicion by the older women:[16] Greeting: We, the members of the Hawaiian Women's Patriotic League, formed for the sole purpose of perpetrating the independence of Hawaii, a kingdom for whom our ancestors fought and bled in war, do hereby implore Your Excellency to recommend to your Government the restoration of our beloved Queen on the throne of Hawaii, and that the present stage should be brought to an end.

[15]On August 9, 1895, cholera arrived in Honolulu aboard the ship Belgic, carrying 500 Chinese immigrants from Yokohama to Hawaii.

[18][19] Efforts were enacted by the Republic of Hawaii's Board of Health to quarantine the sick, restrict large gatherings to lower contact transmissions and enhance hygiene measures in the countryside.

The disease disproportionately affected Native Hawaiians and a subsequent report written by the Board of Health on September 25 indicated that certain taro and rice fields were connected to contaminated water sources.

[22] In the wake of the epidemic, Macfarlane cofounded the Hawaiian Relief Society on September 6, 1895, with fellow Hawaiian civic leaders Bathsheba Robinson Allen, Emma Kaili Metcalf Beckley Nakuina, Elizabeth Kekaʻaniau and Abigail Kuaihelani Campbell to assist the victims of the cholera.

The organization raised funds for the care of patients and provided Hawaiians with food, firewood, clothing and other supplies including sanitized poi boiled in hot water.

Although the Macfarlane sisters were among the leading Hawaiian women to speak at mass meetings in favor of the legislation, the bill stalled.
