On 13 January 1930, "Emden" left Wilhelmshaven on her third voyage abroad. She steamed into the Atlantic and stopped in Madeira before crossing over to tour several ports in the Caribbean, including Saint Thomas in the US Virgin Islands, New Orleans and Charleston in the US, Kingston, Jamaica, and San Juan, Puerto Rico. The ship recrossed the Atlantic, stopping in Las Palmas and Santa Cruz de Tenerife on the way, before arriving back in Wilhelmshaven on 13 May 1930. There, she went into the shipyard for an extensive overhaul. In October, "Fregattenkapitän" ("FK"—Frigate Captain) Robert Witthoeft-Emden took command of the ship.
