The Palazzo Celsi Pollini, once also called the Palazzo del Vescovo, is a Renaissance style urban palace in Siena, Italy.
It is located on Pian dei Mantellini #39-41, at the corner with Via San Quirico.
A 19th-century source refers to the house as Casa Campioni.

The interiors conserve frescoes attributed to the studio of Bartolomeo Neroni, also called il "Riccio", such as a Susanna and the Elders and The Continence of Scipio.
