Hotai Motor Co., Ltd. (Chinese: 和泰汽車; pinyin: Hétài Qìchē) is a Taiwan-based automotive-centric conglomerate.

Traditionally, Hotai is regarded as one of the top four conglomerates and the oldest amongst the "Big Four" business groups in Taiwan.

[1] Hotai Motor can be traced to the founding of its predecessors in China and Japan in 1937 by Lieh-ho Huang.

A few years later, eyeing at the development potential of the transportation industry in Taiwan, Huang went to Japan again to discuss business with local industries and formally registered the company in Taiwan in September 1947, creating the modern entity known today.

In believing that the dairy industry could improve the living standard and nutrition standard of citizens and thereby promote rural economic development and compensate food inadequacy, Wei-Chuan established the dairy product department in the beginning of the 1960s out of the company's insistence on establishing a “public company”.

One of the joint ventures, Formosa Flexible Packaging, moved back to Hotai Motor Group.

Today, the founder Leih-ho Huang was also called the “Father of the Modern Economy” in Taiwan for his contribution and involvement in various aspects of business directly connected to everyday life.

Between 2014 and 2017, Hotai Motor acquired between 20% and 100% of every dealership in the region and part of China for US$580 million and directed the upgrade of the next generation of Toyota and Lexus customer experience.

Today, there are more than 10 foundations focusing on different aspects on charity and form the second largest welfare group in Taiwan with an operating budget in 2018 of US$6.4 billion.
