The coat of arms of the Moldavian ASSR was the official emblem of the Moldavian Autonomous Soviet Socialist Republic in the Soviet Union, and underwent a number of changes over time.
The first coat of arms was adopted in 1925, when the Congress of the Soviets of Ukraine approved on May 10 the Constitution of the Moldavian ASSR. Thus, in section VII, Article 48, the coat of arms was enacted as follows: -"the Moldavian ASSR has its flag and coat of arms, established by the Central Executive Committee and confirmed by the Moldavian Central Executive Committee of the whole Ukraine."
In the meeting of the Presidium of the Central Executive Committee of the Moldavian ASSR, held on 4 September 1925, was decided that the organizational department of the Committee should organize a contest for designing the coat of arms and state flag of the Moldavian ASSR. The projects were to be evaluated by a committee composed of representatives of the Central Executive Committee, of the Agitprop, of the Popular Commissariat of Education and of the Council of trade unions in Moldova. There were established some prizes worth 50 ruble for the first place, 30 ruble for the second one and 20 ruble for third place.
Because of the lack of surviving documents, the results of the contest and the proposed designs are not known. A description of the selected model (which hasn't been found drawn anywhere) is included in the letter from 21 July 1927 of the permanent representative of the Moldavian ASSR near the Government of the Ukrainian SSR, Malcikov: "from the outside, the coat of arms of the Moldavian ASSR shows a wreath of maize stalks and grapes, with a light blue interior over which is displayed a white label. The label contains the map of the Moldavian ASSR, united with Bessarabia. At the bottom of the map, in the center of the wreath, is rising a sun spreading shining rays. On the sun is represented a red star. The wreath is festooned all over with the slogan "Workers of the world, unite!", in three languages - Russian, Ukrainian and Moldavian." These arms therefore contained irredentist symbolism.
