Miller Chapel is the spiritual center of the Princeton Theological Seminary, located in New Jersey, United States, and has been in continuous use since its completion in 1834.

It was built by renowned local architect and builder Charles Steadman in stuccoed brick with a simple Doric portico.

It was designed in the Reformed tradition with one worship space, unifying the choir, congregants, and clergy, and with a central pulpit, emphasizing the proclamation of the Word of God.

An 1874 renovation added Victorian stained glass windows and an organ, moving away from the traditional Reformed aversion to instruments in worship.

The renovation also enlarged the building and removed the Victorian windows so as to restore a more simple appearance, consistent with the Seminary's Reformed heritage.
