Saint Catherine of Alexandria is an oil tempera on beech board painting by Bohemian Gothic painter Master Theodoric.

The whole group of saints, which is placed in the north-eastern niche of the presbytery in the Chapel of the Holy Cross, is characterised by the rich decoration of the drapery.

On a blue azurite ground, six-petalled flowers combined with stylized chrysanthemum are stencilled, accompanied by hand-painted trefoil leaves.

She also had a special personal significance for Charles IV, because on the feast day of St. Catherine, 25 November, he fought a victorious battle at the castle of San Felice in northern Italy in 1332 as a young 16-year-old royal.

In the richly decorated private oratory of Charles IV, adjacent to the Chapel of the Virgin Mary at Karlštejn, there is a mural of St Catherine on the right side of the altar mensa.
