From 1630 onwards, Catholic missionaries made several attempts to enter Laotian territory and preach the Gospel. Most missionary endeavors, however, remained episodic, because they did not result in the establishment of a local Church. The first missionaries were Jesuits who reached Laos from Tongking (Vitenam).

The evangelization efforts of the missionaries of the Paris Foreign Mission Society (MEP), who came to Laos in 1878, were more successful. They succeeded in building up an indigenous Church in Laos. Dec. 8, 1885, the date on which they founded their first mission station, is traditionally accepted as the date of the birth of the Catholic Church in Laos. That mission station was established on Ban Dorn Don, an island in the Mekong River. The Apostolic Vicariate of Laos was founded soon after, in 1899.

Oblate Fathers (OMI) arrived in 1935 and concentrated their missionary work mostly in mountainous tribal areas in the north of the country.

There are approximately 45,000 Catholics, many of whom are ethnic Vietnamese, concentrated in major urban centers and surrounding areas along the Mekong River in the central and southern regions of the country. The Catholic Church has an established presence in five of the most populous central and southern provinces, and Catholics are able to worship openly.

The Catholic Church's activities are more circumscribed in the north. There are four bishops, two located in Vientiane and others located in the cities of Thakhek and Pakse. One of the two bishops resident in Vientiane oversees the Vientiane Diocese and is responsible for the central part of the country. The second bishop resident in Vientiane is the Bishop of Luang Prabang. He is assigned to the northern part of the country, but while the Government did not permit him to take up his post, it did permit him to travel to visit church congregations in the north.

The church's property in Luang Prabang was seized after 1975, and there is no longer a parsonage in that city. An informal Catholic training center in Thakhek prepared a small number of priests to serve the Catholic community. Several foreign nuns temporarily serve in the Vientiane diocese.

There are no dioceses in the country, but it is divided into four Apostolic Vicariates.
