Diamond Castle Holdings is an American private equity firm specializing in leveraged buyout and growth capital investments in middle-market companies.

Founded in 2004, Diamond Castle Holdings was established by Lawrence Schloss and four other senior members of DLJ Merchant Banking Partners (DLJMB) following a spinout from Credit Suisse. The firm operates as an independent private equity house based in New York City, maintaining strong ties to its heritage as a successor to the DLJMB lineage.

The firm focus on investments in middle-market companies, specifically targeting sectors where the leadership has deep expertise. In December 2006, the firm successfully closed its Diamond Castle Partners IV fund with $1.85 billion in capital commitments, naming the fund to reflect the three prior funds managed by the team during their tenure at DLJMB. As of 2011, the firm had raised approximately $1.9 billion since its inception.
