Peter Jalowiczor (born in 1966) is an amateur astronomer living in Rotherham, South Yorkshire, United Kingdom, who has discovered four new planets at home using data released to the public by the University of California's Lick-Carnegie Planet Search Team and has written two books. He has also done further research on comets.

Jalowiczor works in the gas industry in Rotherham, is a member of South Yorkshire's Mexborough and Swinton Astronomical Society, and has two undergraduate degrees from the University of Sheffield - a BSc in physics from 1988 and a PgDip in astrophysical sciences from 1989. He has also authored a book about Millmoor football called Postcards from Millmoor.Rotherham United manager Steve Evans was a guest at the book's launch.

The University of California began uploading its measurements starting in 2005, using the ten meter Keck telescope located in Hawaii. Jalowiczor started his research in 2007, using Doppler spectroscopy. Jalowiczor looked for oscillations of stars in the extensive data released by the University of California that could be caused by a nearby planet, alerting the University of California to possible exoplanets. His work used only two home computers; he has been cited in multiple sources as not owning a telescope.
