Church of Saint James the Greater, Catholic church building in Staré Město, Jičín, Czech Republic.

The Church of Saint James the Greater stands as a three-aisled basilica with an elevated chancel, featuring Baroque architectural elements that dominate its current appearance after extensive 18th-century renovations.

Albrecht von Wallenstein had the church built after 1627 next to his château, on plots of demolished burgher houses, after giving the old parish church to the Jesuits. Giovanni Battista Pieroni designed it; Andrea Spezza led construction until his death in 1628, then Nicolò Sebregondi. Planned as a cathedral for a new bishopric, it was halted after Wallenstein's murder, and the intended dome and four towers were never finished. It was handed over in 1655 and burned in 1681 and 1768.

The interior paintings, including the altarpiece, were made by the Rococo and early Neoclassical painter Josef Kramolín. The dome ceiling carries an illusionistic painting, with the four Evangelists in the spherical triangles beneath it and the four Western Church Fathers under the cornice of the transept. The late Baroque altars of the Virgin Mary and the Sacred Heart come from the Jelínek workshop in Kosmonosy.

The church stands on the square near the Valdická Gate in the historic centre of Jičín, and a Baroque corridor links it directly to the adjoining Valdštejn château. The parish-deanery building sits near the rear of the church. The organ on the choir loft, built in 1903 by Emanuel Štěpán Petr of Prague, was restored between 2004 and 2018.

A mummified forearm displayed near the entrance allegedly belongs to a thief whose arm was caught and severed by a statue of the Virgin Mary during an attempted robbery.
