U hemiji, 2,2,5,5-tetrametiltetrahidrofuran ili 2,2,5,5-tetrametiloksolan je heterociklično jedinjenje sa formulom C
8H
16O, ili (CH3)2(C(CH2)2OC)(CH3)2. Ono se može smatrati derivatom tetrahidrofurana (oksolana) sa dve metil grupe koje zamenjuju atome vodonika na svakom atomu ugljenika u prstenu koji su susedni kiseoniku. Ovo jedinjenje se isto tako može smatrati cikličnim etrom 2,5-dimetilheksana, izomera oktana. Ono se ponekad označava skraćenicama TMTHF ili Me4THF.
Ovo jedinjenje se ponekad koristi kao polarni aprotički rastvarač u hemijskim istraživanjima[6][7] i kao reagens u hemijskoj sintezi.[8]
