The Eroica Trio is an American piano trio consisting of Erika Nickrenz, piano; Susie Park, violin; and Sara Sant'Ambrogio, cello. Park joined the trio in September 2006 to replace founding member Adela Peña. The trio take their name from Beethoven's Eroica Symphony. They have toured and recorded widely and have become one of the most popular trios, both in the United States and abroad. They have released six recordings for Angel/EMI Classics Records, garnering multiple Grammy Award nominations.

Each of the founding members of the trio trained at the Juilliard School. Park is a graduate of the Curtis Institute and studied at the New England Conservatory. In addition to being accomplished musicians, the Eroica Trio have attracted attention in the chamber music world as physically attractive, stylishly dressed women.

The trio took first prize in the prestigious Walter W. Naumburg Chamber Music Competition in 1991. Their first compact disc recording Eroica Trio won National Public Radio's 1997 Performance Today Award for "Debut Recording of the Year."

In addition to touring with a varied piano trio repertoire, the Eroica Trio often appear in concert with major orchestras performing the Beethoven Triple Concerto. They were scheduled to perform that work with the Louisiana Philharmonic Orchestra at the Orpheum Theater in New Orleans in 2005, a performance which was cancelled because of Hurricane Katrina.

The Eroica Trio commissioned a triple concerto by American composer Kevin Kaska. It was premiered by the Saint Louis Symphony Orchestra in November 2001.
