Sno or SNO may refer to:

• SnO, the chemical formula for tin(II) oxide
• "Snö", a song by Laleh
• Sudbury Neutrino Observatory (SNO)
• Small nucleolar RNA (snoRNAs)
• Senecionine N-oxygenase, an enzyme

"Snö" ("Snow") is a song by Iranian-Swedish singer-songwriter Laleh recorded with the London Symphony Orchestra for the film Arn - The Knight Templar. It was released on December 19, 2007 as her ninth single and was later placed on her third studio album, Me and Simon. The song peaked at #14 on the Swedish Singles Chart.

SNO+ is an underground physics experiment under construction (as of Nov 2015) that makes use of the equipment already installed underground for the former Sudbury Neutrino Observatory (SNO) experiment at SNOLAB. The main goals of the project are a search for neutrinoless double beta decay, with secondary measurements of proton–electron–proton (pep) solar neutrinos, geoneutrinos from radioactive decays in the Earth, and reactor neutrinos. It will also be possible to observe supernovae neutrinos if a supernova should occur in our galaxy.

Tin(II) oxide (stannous oxide) is a compound with the formula SnO. It is composed of tin and oxygen where tin has the oxidation state of +2. There are two forms, a stable blue-black form and a metastable red form.
