In 1880, Bly and her family moved to Pittsburgh. An aggressively misogynistic column in the Pittsburgh Dispatch prompted her to write a fiery rebuttal to the editor with the pen name "Lonely Orphan Girl." The editor was so impressed with Bly's earnestness and spirit that he asked the man who wrote the letter to join the paper. When he learned the man was Bly, he refused to give her the job, but she was a good talker and persuaded him. Female newspaper writers at that time customarily used pen names, and for Bly the editor chose "Nellie Bly", adopted from the title character in the popular song "Nelly Bly" by Stephen Foster.

As a writer, Bly focused her early work for the Dispatch on the plight of working women, writing a series of investigative articles on female factory workers. But editorial pressure pushed her to the so-called "women's pages" to cover fashion, society, and gardening, the usual role for female journalists of the day. Dissatisfied with these duties, she took the initiative and traveled to Mexico to serve as a foreign correspondent. Still only 21, she spent nearly half a year reporting the lives and customs of the Mexican people; her dispatches were later published in book form as Six Months in Mexico. In one report, she protested the imprisonment of a local journalist for criticizing the Mexican government, then a dictatorship under Porfirio Díaz. When Mexican authorities learned of Bly's report, they threatened her with arrest, prompting her to leave the country. Safely home, she denounced Díaz as a tyrannical czar suppressing the Mexican people and controlling the press.
