Whether you’re an avid traveler, a history enthusiast, or simply curious about the place you live, discovering the roots of San Diego’s name is a meaningful step towards appreciating its enduring legacy and the many cultures that have contributed to its character.
The Spanish Exploration and the Arrival of San Diego
The origins of San Diego’s name lie in a time of exploration and conquest. When Spanish explorers set foot on California’s shores, they left an indelible mark not just on the land, but also on its place names.
In the mid-16th century, Spanish expeditions were charting the Pacific coast in search of new territories. Among the earliest of these was the voyage of Juan Rodríguez Cabrillo in 1542, who sailed into what is now known as San Diego Bay.
Cabrillo’s landing was significant, but he did not name the region “San Diego.” That moment would come decades later, under a different Spanish flag.
It was Sebastián Vizcaíno, another Spanish explorer, who entered the harbor on November 12, 1602. Vizcaíno was tasked with mapping the California coastline and searching for safe harbors for Spanish galleons returning from the Philippines.
His detailed descriptions of the bay’s beauty and resources were persuasive, but it was his act of naming that would endure through the centuries.
- Juan Rodríguez Cabrillo – First European to arrive in San Diego Bay, 1542
- Sebastián Vizcaíno – Named the bay “San Diego” in 1602
- Spanish expeditions shifted the region’s cultural and geographical landscape
Vizcaíno’s 1602 voyage “brought a new name to a timeless place, forever entwining the city’s story with that of Saint Didacus of Alcalá.”
The naming of San Diego was not just a matter of convenience; it was a reflection of Spain’s broader ambitions and its practice of honoring saints who held significance for the explorers and their homeland.
Honoring Saint Didacus of Alcalá: The Namesake of San Diego
The name “San Diego” is the Spanish version of Saint Didacus of Alcalá, a Franciscan lay brother whose legacy resonated deeply with Spain’s Catholic explorers.
Saint Didacus, also known as San Diego de Alcalá, was born in the 15th century in Spain. Renowned for his humility, miracles, and dedication to the poor, Didacus was canonized in 1588—just years before the naming of San Diego Bay.
The Spanish had a strong tradition of naming places after saints, both to invoke divine protection and to celebrate the Catholic faith.
Vizcaíno arrived in San Diego Bay on November 12, the feast day of Saint Didacus on the Catholic calendar. This timing was no coincidence; it was common for explorers to name new places in honor of the saint celebrated on the day of their arrival.
- Saint Didacus (San Diego) of Alcalá – Canonized in 1588, feast day November 13
- Known for miracles, humility, and service to the sick and poor
- Patron saint of San Diego, California
Why Saints’ Names Mattered
For the Spanish, the act of naming was more than functional—it was spiritual. Naming new lands after saints reflected hopes for divine favor and guidance.
This tradition extended throughout California, with cities like San Francisco, Los Angeles, and Santa Barbara named after revered figures in the Catholic faith. The choice of San Diego for this particular bay was a testament to the profound influence of religious identity on the process of exploration and colonization.

The Mission Era: San Diego’s Name Becomes a Community
The Spanish missions played a pivotal role in cementing the name San Diego in the region’s identity. The founding of Mission San Diego de Alcalá in 1769 marked the beginning of California’s mission era.
This mission, the first in what would become a chain of twenty-one, was named in honor of Saint Didacus. It served as a religious, cultural, and agricultural center, attracting indigenous people and Spanish settlers alike.
The mission’s influence extended from spiritual teachings to language, architecture, and daily life.
The presence of the mission solidified the use of “San Diego” not just for the bay, but for the surrounding area as well. Over time, the mission’s name became synonymous with the city itself, embedding its spiritual and historical roots deep into Southern California soil.
- Mission San Diego de Alcalá was founded by Father Junípero Serra
- First of the California missions, established in 1769
- Became a focal point for early settlement and development
“The name San Diego is forever linked to its mission, a beacon for faith and community on the Pacific coast.”
Impact on Regional Identity
The mission’s name and presence provided a sense of stability and continuity for new arrivals. As settlements grew around the mission, the name San Diego came to represent not just a religious outpost, but a burgeoning community with its own unique blend of traditions and influences.
The mission era’s impact on the region’s culture can still be seen in San Diego’s neighborhoods, festivals, and even its approach to hospitality and community engagement.

From Native Kumeyaay Roots to Spanish Naming
San Diego’s story began long before the Spanish arrived. The region was home to the Kumeyaay people, whose history stretches back thousands of years.
The Kumeyaay called the area “Kosa’aay,” meaning “place of the fish,” and lived in harmony with the land, developing sophisticated systems of trade, agriculture, and governance. When the Spanish first explored the bay, they encountered these indigenous communities and witnessed a way of life deeply connected to the coastal environment.
While the Spanish naming of San Diego reflects one chapter in the city’s history, it is important to acknowledge the enduring presence and influence of the Kumeyaay people. Many contemporary efforts seek to recognize indigenous place names alongside those given by later settlers.
- Kumeyaay village of Kosa’aay predated Spanish arrival
- Indigenous knowledge shaped early Spanish settlements
- Revitalization of native names is gaining momentum today
