Barbara Kolanka or Barbara Kołówna h. Junosza (end of the 15th century–1550) was a Polish noblewoman. She is best known as the mother of queen Barbara Radziwiłł and Mikołaj "the Red" Radziwiłł.
A direct descendant to Elisabeth of Pilcza, the Queen consort to Ladislaus II of Poland, she was born in late 15th century to Paweł Koła (or Kola) of Dalejów and Żółtanice, a prominent Polish politician. Her father was a Chamberlain (since 1490) and castellan of Halicz who in 1502 rose to the rank of Voivod of Podolia. Her mother was Bruneta of Chodcza. She had three older brothers, one of whom (Jan Koła) rose to the rank of Grand Hetman of The Crown.
In ca. 1515 she married Jerzy "Herkules" Radziwiłł. They had three children:[1]
