1,1,3,3-Tetramethyl-1,3-divinyldisiloxane (also referred to as tetramethyldivinyldisiloxane) is the organosilicon compound with the formula O(SiMe₂CH=CH₂)₂.

Tetramethyldivinyldisiloxane is a colorless liquid that is employed as a ligand in organometallic chemistry and also as a homogeneous catalyst.^[1] The ligand is a component of Karstedt's catalyst. It was first prepared by hydrolysis of vinyldimethylmethoxysilane, (CH₂=CH)Me₂SiOMe.^[2]
