John Rojas Jr. (January 6, 1930 – January 22, 2000) was a Chula Vista, California resident who collected and disseminated information about the history of Chula Vista and its foliage.
John Rojas moved to Chula Vista, in 1960 while working as a petty officer in the United States Navy.
Chula Vista is a suburb of San Diego California.
He spent his spare time taking pictures of the homes, meeting people and studying the vegetation and trees in the area.
In 1999, shortly before Rojas' death, the Chula Vista Library Board of Trustees, in recognition of the impact John Rojas had in preserving the history of Chula Vista, presented a resolution creating the John Rojas Local History Room at the Civic Center branch of the library, in order to preserve and makes available materials about the area's historic heritage.
