Fo Guang Shan Hsi Lai Temple (Chinese: 佛光山西來寺; pinyin: Fóguāngshān Xīlái Sì) is a mountain monastery in the northern Puente Hills, Hacienda Heights, Los Angeles County, California.

The planning and construction of the temple in the 1980s was met with suspicion and resistance from local communities, many of whom knew little about Buddhism and had unfounded fears of Buddhist practices.

The main reasons for resistance to the building of the temple were the impact of weekly services, heavy traffic, noise, and concern about environmental damage.

Negative feelings about the building of Hsi Lai have since diminished, as the general level of awareness has been raised and as the temple and its residents have proven to be good neighbors.

In 2008, in celebration of the twentieth anniversary of the opening of Hsi Lai Temple, another international Triple Platform Full Ordination Ceremony for monastics and a Land and Water Dharma Service were held.

The retreats generally consist of classes, meditation, mindful eating through the traditional practice of formal Buddhist dining, and communal chores.

Hsia was eventually convicted by a jury in March 2000 of making five false statements to the Federal Elections Commission and sentenced to 90 days home detention, a fine, and community service.

Twelve nuns and employees of the temple, including then-abbess Venerable Yi Kung who would later resign from the abbotship because of the scandal, refused to answer questions by pleading the Fifth Amendment when they were subpoenaed to testify before Congress in 1997.
