The Antonov Izdelie 181 (Ukrainian: Виріб 181, Russian: изделие 181, sometimes unofficially called An-181) was a Soviet experimental aircraft created in the 1980s.

The izdelie 181 project was terminated due to the lack of funds following the collapse of the Soviet Union.

Power from the engine is delivered by means of drive shafts and deflection gearboxes to the two-blade propellers.

The aircraft received the registration СССР-190101 and is exhibited in the State Museum of Aviation of Ukraine.

Willard Ray Custer had previously built aeroplanes with the same wing concept in the USA.
