The 39-year-old Federer beat Cameron Norrie 6-4 6-4 5-7 6-4 on Centre Court.
The eight-time Wimbledon champion had a slight wobble in the third set when he missed two break points at 5-5 and was then broken at love by Norrie.
After trading breaks in the fourth set, Federer broke again for a 5-4 lead.
He will play No 23-seeded Lorenzo Sonego of Italy on Monday.
It's the 69th time that Federer has reached the fourth round of a Grand Slam tournament, also a record.
