Pheasant Creek is a perennial to intermittent 1.8 miles (2.9 km) north-by-northeast flowing stream in Santa Clara County, California, United States.

Pheasant Creek and the rest of the upper Guadalupe River watershed below the Guadalupe Reservoir and Dam were near the Guadalupe Mine, part of the New Almaden Mercury Mining District, established in 1845 in the hills south of San Jose, California, which hosted the first and most productive mercury mines in the state.

[2] According to numerous reports, Pheasant Creek's lower reaches host spawning steelhead trout (Oncorhynchus mykiss).

[7] A 2014–2015 steelhead trout survey found "Guadalupe Creek above Hicks Road had the longest contiguous area of flowing freshwater" with appropriate conditions for residence of O. mykiss in the Guadalupe River watershed, with the highest catch rate near the mouth of Pheasant Creek.

[4] The entire Pheasant Creek watershed is protected on Sierra Azul Open Space Preserve lands.
