Sister Clare Crockett (1982–2016) was a Catholic religious sister from Derry, Northern Ireland, who transitioned from a budding career in acting to a life of devoted service. From a young age, she exhibited a passion for the arts, securing roles in theater and television. However, a profound spiritual experience during a Good Friday service in Spain in 2000 led her to reevaluate her life's direction. By 2001, at the age of 18, she joined the Servant Sisters of the Home of the Mother, embracing a vocation dedicated to faith and community.

In her religious life, Sister Clare served in various countries, including Spain, the United States, and Ecuador, engaging in pastoral care, teaching, and missionary outreach. She was particularly known for her vibrant personality and ability to connect with young people, often using her artistic talents to inspire and educate. Her commitment to her faith and the communities she served was evident in her daily interactions and the profound impact she had on those around her.

Tragically, on April 16, 2016, Sister Clare lost her life during an earthquake in Playa Prieta, Ecuador, while attempting to ensure the safety of others. Her untimely death at the age of 33 was widely mourned, and her legacy continues to inspire many. A documentary titled "All or Nothing: Sister Clare Crockett" was later produced, highlighting her journey from aspiring actress to devoted nun, encapsulating her motto of giving everything for her faith.
