This is a list of my favorite 12 orders of Catholic nuns and sisters in no particular order. This list includes their history, and images of their habits.

What is a Catholic Nun or Sister?

In the Roman Catholic tradition, there are many religious institutes of nuns and sisters (the female equivalent of male monks or friars), each with its own charism or special character. Nuns, religious sisters, and canonesses all use the term "Sister" as a form of address.

What is a Nun?

Traditionally, a nun is a woman who vows to dedicate her life to religious service and contemplation, typically living under the solemn vows of poverty, chastity, and obedience in the enclosure of a monastery or convent.

What is a Sister?

The HarperCollins Encyclopedia of Catholicism (1995) defines "congregations of sisters [as] institutes of women who profess the simple vows of poverty, chastity, and obedience, live a common life, and are engaged in ministering to the needs of society."


What is a Habit?

A religious habit is a distinctive set of religious clothing worn by members of a religious order. Traditionally some plain garb recognizable as a religious habit has also been worn by those leading the religious eremitic and anchoritic life, although in their case without conformity to a particular uniform style. The religious habits of Roman Catholic nuns typically consist of the following elements:

  1. Tunic: This is the central piece of the habit. It is a loose dress made of serge fabric pleated at the neck and draped to the ground. It can be worn pinned up in the front or in the back to allow the nun to work.
  2. Scapular: This symbolic apron hangs from both front and back; it is worn over the tunic, and Benedictine nuns also wear it over the belt, whereas some other orders wear it tied under the belt.
  3. Cincture: The habit is often secured around the waist with a belt of leather, wool, or a lanyard. The cincture of the Franciscan orders has three (or four) knots standing for the vows.
  4. Coif: This is the garment's headpiece and includes the white cotton cap secured by a bandeau and a white wimple (to cover the neck and cheeks) and guimpe (to cover the chest, similar to a short cape) of starched linen, cotton, or (today) polyester. It is sometimes covered by a thin layer of black crêpe.
  5. Veil: This element is worn pinned over the coif head coverings. Some veils can be worn down to cover the face or up to expose it. The veil sometimes includes a white underveil as well. The color of the veil depends as well on the habit of the order and the status of the sister or nun (novices or postulants wear differently colored veils than the professed sisters and nuns).

The coif and veil were common items of clothing for married women in medieval Europe.

Different orders adhere to different styles of dress; these styles have changed over time. The religious habit of Roman Catholic sisters sometimes consists of a plain dress and a veil.

The Discalced or Reformed Carmelite, a branch of the Order of Our Lady of Mount Carmel, was founded by St. Teresa of Avila, in 1562. Before her death, she established 16 Monasteries of Nuns. The first monastery of the Second Order of Carmel was established in the U.S. in 1790.

6. Sisters of Notre Dame de Namur

7. Oblate Sisters of Providence

The Institution of the Sisters of Notre Dame de Namur was founded in Amiens, France, in 1803 by Blessed Julie Billiart. Later the Motherhouse was transferred to Namur, Belgium - hence the name. From there the Sisters established foundations in England, Scotland, Italy, Belgian Congo, South Africa, China, Japan, Hawaii, and the United States, (where the first school opened in Cincinnati, Ohio, in 1840). The Sisters of Notre Dame de Namur are primarily a teaching order.

The Oblate Sisters of Providence (the First Black Community in the United States) was founded by Father James Joubert and Mother Mary Elizabeth Lange on July 2, 1829, in Baltimore, Maryland. In the lower chapel of old St. Mary's Seminary, Fr. Joubert taught catechism to the children of African heritage. He found this a difficult task when faced with underprivileged children who could not read or write, they inspired him to organize a school and congregation of women devoted to teaching.

8. Missionary Sisters

9. Little Sisters of the Poor

The Missionaries of Charity were founded in India in 1950, by Mary Teresa Bejaxhiu. The Sisters serve the poorest of the poor throughout the world. In the United States, they maintain five Centers of Formation, as well as many soup kitchens, shelters, camps for poor children, homes for the dying, and other ministries. The order survives on the Love of God and by donations given by persons of all faiths.

The Little Sisters of the Poor provided homes, and care for the aged poor. Inspired by the love of God and the love of His Poor, the Little Sisters of the Poor add to the vows of Poverty, Chastity, and Obedience the Vow of Hospitality. The black mantle is worn over the habit in the Chapel and when traveling. The headdress is a plain white bonnet with a forehead band as a symbol of obedience.

10. Daughters of Wisdom

11. Sisters of the Order of St. Benedict

12. Poor Clare Nuns

The Congregation of the Daughters of Wisdom was founded on February 2, 1703, by St. Louis-Marie de Montfort who invested Marie-Louise Trichet as the first Daughter of Wisdom. Their habit is made of coarse gray serge. A large linen handkerchief covers the shoulders, and a starched white linen headdress is worn instead of a veil. The habit became a symbol of Christ's love as the sisters worked tirelessly among the poor and sick; later it became a symbol of faith and courage as the sisters mounted the scaffold to their deaths during the days of the French Revolution.

The Order of St. Benedict has its motto, “That in all things God may be glorified.” The order was founded by St. Benedict in the fifth century. The Benedictine Order is one of the world's oldest religious orders and is found throughout the world. The first American congregation began at St. Mary's Convent, Pennsylvania. Their life is contemplative with the sanctification of her soul through dedication to Christ.

Saint Clare of Assisi (1194-1253), was the first Abbess of the Order of Poor Clares at San Damiano, Assisi, in Italy. At the age of eighteen, this young heroine vowed herself to the service of Jesus Christ and received her habit from Saint Francis of Assisi himself, in 1212. Thus was instituted the Order of Poor Clares, of the Second Order of St. Francis.
