Ogończyk is a Polish coat of arms. It was used by several szlachta families in the times of the Kingdom of Poland and the Polish–Lithuanian Commonwealth.

Although the coat of arms was first mentioned in an armorial of 1384, it is probable that it stems from early mediaeval Slavic signs for marking the cattle. After the Union of Horodło of 1413 several Lithuanian boyar families were adopted to it. With time it also spread to Prussia, where several Germanized families used it.

Gules, half an argent arrow heading upwards, supported by half of a ring. Out of the crest coronet two bare maiden hands (sometimes armed hands), holding a ring, all proper.
