Tin(II) 2-ethylhexanoate or tin(II) octoate or stannous octoate (Sn(Oct)₂)^[1] is a compound of tin. Produced by the reaction of tin(II) oxide and 2-ethylhexanoic acid, it is a clear liquid at room temperature, though often appears yellow due to impurities, likely resulting from oxidation of Sn(II) to Sn(IV).^[2]

It is sometimes used as a polymerization catalyst, such as for the production of polylactic acid.^[3]
