Top 10 Richest Men In Indonesia According To Forbes (2025)

When you think of billionaires, countries like the United States, China, and India might first come to mind. But Indonesia—Southeast Asia's largest economy—is no stranger to extraordinary wealth. As of Forbes' 2025 ranking, the archipelago nation is home to some of the world’s most influential and wealthy business magnates. These individuals have amassed their fortunes through industries such as coal, banking, tobacco, energy, petrochemicals, and even data centers.

In this article, we’ll dive into the lives, empires, and economic impact of the top 10 richest men in Indonesia, as ranked by Forbes in 2025.

1. Low Tuck Kwong – $27.3 Billion

At 76, Low Tuck Kwong holds the prestigious title of Indonesia's richest man. He is the founder of Bayan Resources, one of Indonesia’s largest coal producers. Born in Singapore but now an Indonesian citizen, Low made his mark in the energy sector by capitalizing on Indonesia’s abundant natural resources.

His net worth of $27.3 billion is largely attributed to the global demand for coal, especially in Asia, where energy consumption continues to soar. Despite global movements toward renewable energy, Low's empire remains highly profitable.
