What Does Silas Mean?
At its core, the name Silas is a celebration of nature. The name translates to “of the forest,” “god of trees,” or simply “wood forest.” Etymologically, it is the Greek nickname for the Latin name Silvanus. The Latin root word silva means “wood” or “forest,” giving the name a deep, organic connection to the earth.
Because of this meaning, Silas sits comfortably at the intersection of religious history and pagan nature worship. It acts as a more subtle, historical alternative to literal nature names like River or Bear. If you are looking for a strong name that implies resilience and growth without sounding aggressive, Silas fits the bill perfectly.
Where Does the Name Silas Come From?
The name Silas has a dual origin story that spans both the Bible and Roman mythology.
The Biblical Connection:
Silas is a prominent figure in the New Testament. He was a leading member of the early Christian community in Jerusalem and a companion of Paul the Apostle. He famously accompanied Paul on his second missionary journey and was imprisoned with him in Philippi. In the Bible, he is sometimes referred to by the longer Roman form, Silvanus.
The Roman Connection:
The name is likely derived from the name of the Roman god Silvanus. In Roman religion, Silvanus was the tutelary spirit (guardian) of the woods and uncultivated lands. He is similar to the more popular Faunus, the god of animals, with whom he is sometimes merged (1).
While the Puritans revived the name in the 16th and 17th centuries as an act of humility, choosing lesser-known Biblical figures, it is the modern appreciation for its soft, melodic sound that has kept it alive today.
How Popular is the Name Silas?
Silas is currently experiencing a “Golden Age” of popularity. For much of the 20th century, Silas was considered a dusty, “old man” name, hovering low on the charts or dropping off them entirely. However, the name began a slow climb in the 1990s and skyrocketed in the 2000s.
According to SSA data (2), Silas cracked the US Top 100 for the first time recently and has firmly established itself as a “Modern Classic.”
Much of this momentum can be attributed to the “Justin Timberlake Effect” (he named his son Silas in 2015), as well as the broader trend of parents seeking vintage names ending in “s” (like Miles and Elias). It is no longer a rare oddity; it is a beloved favorite.
Is Silas a Boy or Girl Name?
Silas is traditionally and overwhelmingly a male name. Its roots in the Bible and Roman history are strictly masculine. While modern naming trends often see traditional boy names crossing over to girls (like James or Noah), Silas has largely remained distinct to boys.
However, the “vibe” of the name is soft and approachable rather than hyper-masculine. If you love the sound but want something for a daughter, you might consider the related name Silvia (or Sylvia), which shares the exact same “of the forest” etymology.
How Do I Pronounce Silas?
The most common English pronunciation is SIGH-liss or SIGH-lus.
The emphasis is always on the first syllable.
- Phonetic: SY-ləs
While the pronunciation is straightforward, regional accents may flatten the second syllable to sound more like “less” or open it up to sound more like “lass,” though “Sigh-lus” is the standard expectation.

FAQs About the Name Silas
How Old Is the Name Silas?
Silas is ancient. While it became popular in English during the Protestant Reformation (16th century), the name dates back to the first century AD in the Bible (as a companion of Paul) and even further back to pre-Christian Roman mythology via the god Silvanus.
What Is Silas in Hebrew?
Silas is a Greek/Latin name, not Hebrew. However, in the Bible, the companion of Paul is often associated with the Hebrew name Saul (Sha’ul). While they are distinct names etymologically, many scholars believe Silas may have been the Greek name chosen by the Jewish Saul to use among gentiles.
What Does Silas Mean Spiritually?
Spiritually, Silas represents faithfulness and companionship. In the Bible, Silas stayed with Paul in prison, singing hymns despite their chains. The name also connects spiritually to stewardship of the earth, due to its root meaning “of the forest,” linking it to nature-focused spiritualism.
Is Silas a Villain Name?
Silas has occasionally been used for villains in pop culture (like in “The Da Vinci Code” or “The Vampire Diaries”) because the “S” sounds can be made to sound sinister or serpentine. However, in real life usage, the name is viewed as gentle, scholarly, and rugged rather than evil.
Is the Name Silas Too Popular?
Silas is popular, but not “overexposed” like Liam or Noah. While it sits comfortably in the Top 100, it is not generally a name where you will find three of them in the same kindergarten class. It hits the “sweet spot” of being recognizable and spelled correctly by everyone, without being ubiquitous.
What Are Good Nicknames for Silas?
Aside from the obvious “Si” (pronounced Sigh), parents looking for something unique often use “Sly.” It adds a bit of mischievous charm to an otherwise serious name. Some families also use “Sy” or the playful “Si-Guy.”
Does Silas Appear in the Old Testament?
No, the name Silas appears only in the New Testament. It is strictly associated with the early Christian church and the missionary journeys of Paul. The closest Old Testament equivalent in terms of usage/persona would be Saul.
Can Silas Be a Girl’s Name?
Technically any name can be unisex, but Silas is statistically and historically male. If you want a similar sound and meaning for a girl, the name “Silvia” (or Sylvia) is the direct feminine equivalent, sharing the exact same Latin root for “forest.”
