Jeddo is a borough in Luzerne County, Pennsylvania, United States. As of the 2020 census, the population was 109, making it the least populous borough in the county.

The Pennsylvania village was originally known as "Japan-Jeddo," after the Japanese port of Edo (anglicized to Jeddo, Japan). When it was incorporated as a Pennsylvania borough (on October 23, 1871), it was renamed "Jeddo." However, some people still referred to it as "Japan-Jeddo." This unofficial name was used up until the 1941 surprise attack on Pearl Harbor, which triggered the United States to enter World War II. After the Japanese attack, the locals dropped the unofficial name ("Japan-Jeddo") and only referred to it as "Jeddo."
