Operation Kraai (Operation Crow) was a Dutch military offensive against the de facto Republic of Indonesia in December 1948 after negotiations failed. With the advantage of surprise the Dutch managed to capture the Indonesian Republic's temporary capital, Yogyakarta, and seized Indonesian leaders such as de facto Republican President Sukarno. This apparent military success was however followed by guerrilla warfare, while the violation of the Renville Agreement ceasefire diplomatically isolated the Dutch, leading to the Dutch–Indonesian Round Table Conference and recognition of the United States of Indonesia.

Referred as the second Politionele acties by the Dutch, it is more commonly known in Indonesian history books and military records as Agresi Militer Belanda II (Dutch Military Aggression II).
