Syncaris pasadenae was a species of shrimp in the family Atyidae, which is believed to be extinct.

It lived in the drainage basin of the Los Angeles River, near Pasadena, San Gabriel and Warm Creek, and was originally described from material collected on the site where the Rose Bowl now stands. A reference to "freshwater shrimps" in a tributary of the Santa Ana River from 1927 may also refer to S. pasadenae.

Its habitat was destroyed by channelization of streams. It has not been seen alive since 1933, despite extensive searching, and is the only Recent species of shrimp to have gone extinct.
