Shravana (Devanagari: श्रवण), also known as Thiruvonam in Tamil and Malayalam (Tamil: திருவோணம், Malayalam: തിരുവോണം), is the 22nd nakshatra or lunar mansion as used in Hindu astronomy, Hindu calendar and Hindu astrology. It belongs to the constellation Makara (Devanagari: मकर), a legendary sea creature resembling a crocodile] or Capricorn. The name alludes to Shravan, a mythological character who attained repute due to his utmost devotion to his aged and blind parents.
Lord Venkateswara of Tirupati and Lord Oppiliappan near Kumbakonam, who married Markandeya Rishi's daughter Bhuvalli, are believed to be born in this Nakshatra in the Bhadrapada maasa. Onam, the biggest festival of Kerala, is celebrated on this Nakshathra in the Malayalam month of Chingam.
