William Westley Guth (October 15, 1871 – April 19, 1929) was an American attorney, Methodist minister, and academic who served as the fourth president of Goucher College.

He practiced law in California for several years and then continued his studies at Boston University, earning a Bachelor of Sacred Theology and becoming ordained as a Methodist minister.

During his tenure, Guth orchestrated the construction of several new residence halls, including the Alumnae Lodge, and a successful million-dollar fundraising campaign, which enabled the college to reduce its debts, augment its endowment, and purchase the plot of land that would eventually become its Towson campus.

I beg that you will believe I am prompted to write this letter only by genuine regard for a man whom I very much esteem and without the least desire to thrust my counsel, uninvited, into the deliberations of the authorities of the college.

"[5] By 1920, Guth had grown increasingly concerned about the continued viability of the college's Baltimore campus and had begun, with the consent of Goucher's board of trustees, searching for a suitable location in the nearby suburbs.

Faculty member Hans Froelicher, whom Guth had previously dismissed, was appointed in his place as acting president as the college searched for a successor.
