The Negro Motorist Green Book, commonly known as the Green Book, was an annual guidebook for Black travelers in the United States during the Jim Crow era. It was first published in 1936 by Victor Hugo Green, a Black postal worker from Harlem, New York. The Green Book provided information about safe places where Black travelers could eat, sleep, shop, and be entertained without facing discrimination or danger.

The Green Book played a crucial role in ensuring the safety and comfort of Black travelers during a time when segregation and racism were rampant across the country. It listed Black-owned businesses, hotels, restaurants, and other establishments that welcomed Black customers, helping them navigate through regions where they might encounter hostility or denial of service. The Green Book also included tips on how to travel safely and avoid potential dangers while on the road.

The publication of the Green Book ceased in 1967, following the passing of the Civil Rights Act of 1964, which outlawed segregation and discrimination based on race, color, religion, sex, or national origin. While the Green Book is no longer necessary for safe travel, it remains an important symbol of resistance and resilience in the face of systemic racism and discrimination.
