四泉圣嘉禄堂或称四喷泉圣卡罗教堂（意大利语：Chiesa di San Carlo alle Quattro Fontane或 San Carlino）是一座位于意大利罗马的天主教教堂，由建筑师博罗米尼设计，修建于1638年至1641年。此外，这座教堂为巴罗克风格建筑的杰作，是奎利那雷山上巴贝里尼枢机主教建筑群的一部分。教堂坐落在斐理斯路和皮亚路交界处的狭小地基上，因此设计了十字平面和不平常的凸凹形的正立面。教堂椭圆形的穹顶为25.8米乘16.25米，而装饰就以复杂的几何形体（十字形、椭圆形、八角形及六角形）组成。

The church of San Carlo alle Quattro Fontane (Saint Charles at the Four Fountains), also called San Carlino, is a Roman Catholic church in Rome, Italy. The church was designed by the architect Francesco Borromini and it was his first independent commission. It is an iconic masterpiece of Baroque architecture, built as part of a complex of monastic buildings on the Quirinal Hill for the Spanish Trinitarians, an order dedicated to the freeing of Christian slaves. He received the commission in 1634, under the patronage of Cardinal Francesco Barberini, whose palace was across the road. However, this financial backing did not last and subsequently the building project suffered various financial difficulties. It is one of at least three churches in Rome dedicated to San Carlo, including San Carlo ai Catinari and San Carlo al Corso.
