Tassajara Creek Regional Park (TCRP) is a park near Dublin in the U.S. state of California, which has been called one of the most obscure parks in the East Bay Regional Park System.Samson, Samuel. "[https://patch.com/california/livermore/tassajara-creek-a-hikers-training-grounds "Tassajara Creek: A Hiker’s Training Grounds]". Livermore Patch. August 1, 2011. Accessed August 22, 2017. It is located adjacent to the eastern boundary of Camp Parks and was established in 1991 as a staging facility for the Tassajara Creek Regional Trail. Because of TCRP's small size—{{convert|27|acres|ha}}—and the existence of a security fence along the Camp Parks boundary, usage of the park by both humans and wildlife is limited.[https://books.google.com/books?id=otU3AQAAMAAJ&dq=tassajara+creek+regional+park&pg=PA89 Master Planned Redevelopment at Camp Parks: Final Environmental Impact Statement. July, 2009. p.89. Available on Google Books.] Accessed August 24, 2017.

Amenities are minimal. There is just one picnic table and one short hiking trail, but the venue is rarely crowded. One writer opined that TCRP filled a worthwhile niche in the park district's offerings, saying that "this is a very friendly spot for young children and puppies to experience a first hike".
