赫尔曼·何乐礼（英语：Herman Hollerith，1860年2月29日－1929年11月17日）或译赫尔曼·霍尔瑞斯，是一位德裔美籍的统计学家和发明家。基于打孔卡技术，他发明了打孔卡片制表机（Tabulation Machine）。他也是制表机器公司（Tabulating Machine Company）的创办者，该公司是IBM的前身之一。何乐礼被广泛认为是现代机械数据处理之父。 随着他发明的制表机，自动数据处理的时代开启。

Herman Hollerith (February 29, 1860 – November 17, 1929) was an American inventor who developed an electromechanical punched card tabulator to assist in summarizing information and, later, accounting. He was the founder of The Tabulating Machine Company that was consolidated in 1911 with three other companies to form the Computing-Tabulating-Recording Company, later renamed IBM. Hollerith is regarded as one of the seminal figures in the development of data processing. His invention of the punched card tabulating machine marks the beginning of the era of semiautomatic data processing systems, and his concept dominated that landscape for nearly a century.
