Przyjaciel (Polish for "Friend") also known as "de Pryjatel" and "Amicus" is a Polish coat of arms. It was used by several szlachta (noble) families under the Kingdom of Poland and the Polish–Lithuanian Commonwealth.

The coat of arms has its source in the following historical event during the reign of the Polish King, Bolesław IV the Curly (Kędzierzawy) (1125-1173), Duke Henryk, Prince of Sandomierz, the king's brother, was waging war against the still pagan Prussians, in 1164, and was killed in a battle. The knight Mirosław, who hailed from the east, as his name suggests, and who was in the service of the king and king's brother, Henryk, broke through the enemy lines with his men, in order to retrieve Henryk's body and valuable armor, but was killed himself in the process. For Mirosław's steadfast loyalty, in the memory of his bravery, King Bolesław of Poland bestowed this coat of arms and lands to Mirosław's descendants.^[1]

A shield of blue color, with a heart in a vessel, pierced from top to bottom by an arrow, helmet with five ostrich feathers, and the blue and yellow fringe, signifying the ancient colors of knight Mirosław's ancestral origins.
