Sandeep or Sundeep (Devanagari: सन्दीप् sandīp or संदीप् saṃdīp) is a popular Indian and Nepali name. It can be divided into two elements: sat (or saṃ) and dīp. Sat refers to goodness or virtue, and dīp refers to a light. Saṃdīp, or Sandeep, is formed when these two words are combined through the grammatical process of sandhi. Thus, Sandeep is interpreted to mean "a virtuous light." The name may also refer to enlightenment; the word saṃdīp in Sanskrit can mean "enlightened. It is also possible that the name is derived from Sundeepan, or Sandeepani Muni."
It is primarily used by men and women from Hindu or Sikh backgrounds. Among Hindus, the name is mostly used by men. Among Sikhs, the name Sandeep can be used for both males and females; the name itself has no gender bias. Its origin is from sanskrit "sandeep" who was the guru of Lord Krishna.
