Ong Dia is a god of Vietnamese tradition.
The smiling earth god who watches over house and plot.
Ong Dia is the Vietnamese earth and house god, the protective lord of plot and house. As a stout, broadly smiling man with a palm-leaf fan, he preserves peace and protection and, together with the god of wealth Than Tai, brings prosperity and business fortune.
His cult is shaped by the Chinese Tudigong earth god cult and interwoven with Taoism, Confucianism and ancestor worship. He is venerated at a floor-level altar near the entrance door, in Vietnam as well as in the diaspora.

The cult belongs to Vietnamese folk religion; it is shaped by the Chinese Tudigong earth god cult and interwoven with Taoism, Confucianism and ancestor worship.
Vietnam and the Vietnamese diaspora: floor altars for Ong Dia are found in shops, restaurants and households.
Well documented: the classic studies by Léopold Cadière and Toan Ánh, as well as more recent research on the Vietnamese kitchen god complex.
Vietnamese: The name combines ong, lord or grandfather, with Dia, Sino-Vietnamese for earth. Related terms are Tho Dia, earth god, and Tho Cong, earth lord, which largely refer to the same local deity.
Appearance
Ong Dia is typically depicted as a fat, bare-bellied man with a broad smile, often holding a palm-leaf fan. He is clearly distinct from the wealth god Than Tai, who appears clothed, white-bearded, and carrying gold bars.
Effect
Ong Dia is an earth god and protective lord of land and house: he preserves peace and protection, and together with Than Tai brings prosperity and business fortune.
The key aspects of the earth god at a glance.
Sino-Vietnamese syncretism: emerged from the Chinese Tudigong cult and interwoven with Taoism, Confucianism and ancestor worship.
Land and house: Ong Dia preserves peace and protection and brings prosperity and business fortune, especially in shops and restaurants.
A fat, bare-bellied man with a broad smile and a palm-leaf fan; not to be confused with the clothed, white-bearded Than Tai carrying gold bars.
Protective lord of the land and bringer of prosperity, very often venerated together with the wealth god Than Tai at a double altar.
A low altar near the entrance door; daily offerings are incense, water, fruit, tea and occasionally cigarettes.
The Chinese Tudigong as origin, the Thai Phra Phum with his spirit house, the Roman genius loci, and the kitchen god complex Tao Quan.
The name Ong Dia combines ong, lord or grandfather, with Dia, Sino-Vietnamese for earth; related terms are Tho Dia, earth god, and Tho Cong, earth lord, which largely refer to the same local deity.
The cult is shaped by the Chinese Tudigong earth-god cult and interwoven with Taoism, Confucianism and ancestor worship; its roots are Sino-Vietnamese, not purely Vietnamese. This entanglement also explains the conceptual blurriness: Tho Cong, Tho Dia and the kitchen god complex overlap and are defined differently depending on the region.
Ground altars for Ong Dia are found in Vietnamese shops, restaurants and households, both in Vietnam and in the diaspora. The masked fat, smiling man with a fan who leads the lion in the lion dance is the same Ong Dia, his most popular manifestation.
In religious studies terms, Ong Dia is a benevolent earth and household god. Three clarifications: the cult is a syncretism of indigenous animism and Chinese folk religion, not purely Vietnamese. The terms Tho Cong, Tho Dia and the kitchen god complex overlap and are defined differently depending on the region. And the exact placement of Tho Cong within the kitchen god trio is not resolved uniformly in the literature.
Ong Dia is venerated at a low altar near the entrance door, not high up like the ancestor altar, very often together with Than Tai, especially in shops and restaurants. Daily offerings are incense, water, fruit, tea and occasionally cigarettes. The 10th day of the first lunar month, Via Than Tai, is the great day of the double altar, when many people buy gold.
Related figures are the Chinese Tudigong, from whom the cult originated, the Thai Phra Phum with his spirit house San Phra Phum, and the Roman genius loci. Within Vietnam, Ong Dia stands alongside the kitchen god complex Tao Quan, with which his name Tho Cong partly overlaps; the kitchen god motif is covered on the page about the Chinese Zao Jun.

As both Vietnamese earth god and household god, Ong Dia shows how closely protection and prosperity sit together in Vietnamese daily life: down on the ground, near the door, with a broad smile.
