Sir Thomas Burch Western CavTE, 1st Baronet (22 August 1795 – 30 May 1873) was an English Liberal Party politician.
He served as High Sheriff of Essex for 1850. He was elected at the 1865 general election as Member of Parliament (MP) for the Northern division of Essex. When Essex was divided into three divisions (rather than two) for the 1868 general election, Western stood in the new Eastern division, but did not win a seat.
He was Lord Lieutenant of Essex from 1869 to 1873.
