Syncaris pasadenae is an extinct species of freshwater shrimp in the family Atyidae.[2]

It lived in the drainage basin of the Los Angeles River, near Pasadena, San Gabriel and Warm Creek,[3] and was originally described from material collected on the site where the Rose Bowl now stands.[4] 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.[4] It has not been seen alive since 1933, despite extensive searching, and is the only recent species of shrimp known to have gone extinct.[5]
