The 51-year-old presents The Chris Evans Breakfast Show on BBC Radio 2 every weekday morning but less people have been tuning in.
In the second quarter of 2017, the star pulled in 9.01million listeners a week compared to 9.47million in the same timed period in 2016, according to the latest figures released by audience research body Rajar.
It comes after the former Top Gear host received backlash for toping the list of BBC’s highest-paid stars with a salary bracket of £2.2million to £2.49million.
Elsewhere, Nick Grimshaw’s breakfast show on BBC Radio 1 has seen a huge increase in recent months with an extra 350,000 listeners tuning in.
The 32-year-old drew in 5.5million weekly listeners in the second quarter of this year, compared to 5.14million in the first.
BBC Radio 4’s Today programme saw the biggest surge in listeners, with the news show pulling in 7.66million a week in the second quarter, compared to 7.13 million in the first three months of the year.
Every week, 11.55million people are tuning in to the station’s programmes compared to 11.11million in the previous quarter and 11.51 million last year.

Bob Shennan, director of BBC radio and music, said: “These figures are fantastic news for radio, illustrating its enduring appeal in a crowded digital marketplace.
“Radio 4 remains as vital as ever as it approaches its 50th anniversary. Its success highlights the importance of first-class, trusted news in turbulent times, but also the strength the station has across its schedule with a unique mix of programmes.
“Hats off to all at Radio 1. Their half a million gain is a real boost and owes much to the hard work all the teams have put in to making the listening experience better than ever.”
