Thomas Asbury Morris (April 28, 1794 – September 2, 1874) was an American bishop of the Methodist Episcopal Church, elected in 1836.

He also distinguished himself as a Methodist circuit rider, pastor, and presiding elder, and as an editor.

Before reaching manhood Thomas served three years as an assistant in the office of his brother Edmund, who was County Clerk.

At the age of eighteen, Thomas was drafted to serve a six-month term in the War of 1812.

Owing to his youth, however, his family obtained a substitute for him, thereby allowing him to avoid military service (as was common in that day).

In 1820 he was placed in a supernumerary relation, but was sent to Lancaster, Ohio (at that time, a newly constituted station).

That year he also suffered from a shock of paralysis, and was afterwards transferred back to the Ohio Conference.

In spite of impaired health, however, he remained a dedicated student and a wide reader.

In April 1834 he was appointed editor of the Western Christian Advocate, an important periodical of his denomination, headquartered in Cincinnati, Ohio.

He was diligent and faithful in the discharge of all his duties, traveling extensively through the circuit of the Annual Conferences, which then embraced the whole of the settled part of the U.S.A.
