Robert Eugene Stacey Jr. (c. 1950 – September 8, 2022) was an Oregon attorney and leader in land-use and transportation planning.

On his death, Congressman Earl Blumenauer stated that "Oregon just lost the most important person that most people have never heard of".

During this time, he was instrumental in arguing in favor of land-use planning law such as the new urban growth boundary system to preserve farmland and combat suburban sprawl.

[4] Stacey also participated in legal action against Rajneeshpuram, which resulted in a suspected poisoning attempt against him and 1000 Friends of Oregon staff during the same period that Rajneeshees perpetrated a 1984 bioterror attack and 1985 assassination plot.

[6][7] In 2021, a pedestrian and cyclist bridge in Portland, the Gideon Overcrossing, was renamed the Bob Stacey Crossing in his honor.
