Syncaris pasadenae was a species of shrimp in the family Atyidae, which is believed to be extinct.[1]

It lived in the drainage basin of the Los Angeles River, near Pasadena, San Gabriel and Warm Creek,[2] and was originally described from material collected on the site where the Rose Bowl now stands.[3] 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.[3] It has not been seen alive since 1933, despite extensive searching, and is the only Recent species of shrimp to have gone extinct.[4]
