Henry John Hefty (December 28, 1858 – August 20, 1915) was an immigrant from Switzerland who worked as an architect based in Portland, Oregon, United States.

He designed Portland's First Congregational Church at SW Park and Madison Street, and he supervised its construction between 1889 and 1895.

His design was massive, and its construction required a major amount of stone, iron, and brick over a two-year period at a cost of $500,000.

[7] After the building's foundation was completed, the city council stopped construction, citing cost overruns.

The council awarded a new contract to architects Whidden & Lewis to design a less costly, more modest building.
