Castle Harlan is a New York-based private equity firm that specializes in control investments in middle-market companies.

Founded in 1987 by John K. Castle and Leonard M. Harlan, Castle Harlan has a history rooted in the early private equity activities of Donaldson Lufkin & Jenrette. The firm specializes in middle-market buyouts and growth capital investments across a variety of sectors. Since its inception, the firm's investment managers have completed over 50 acquisitions with a total value of approximately $10 billion.

The firm operates both domestically in the United States and internationally. In 1999, it expanded into the Asia-Pacific region by partnering with Australian Mezzanine Investments to form Castle Harlan Australian Mezzanine Partners (CHAMP), focusing on middle-market businesses in Australia and Southeast Asia. The firm also maintains a close relationship with Branford Castle, an affiliate focused on companies with less than $100 million in annual sales.

Castle Harlan is known for managing several investment funds, including its flagship Castle Harlan Partners series, which have attracted billions in equity commitments. Notable recent activity includes the acquisition of oil and gas production assets to form Titan Production Equipment and the purchase of spray tanning equipment manufacturer Sunless Inc. The firm has a track record of acquiring platform businesses that have collectively reached over $11 billion in enterprise value.
