A vehicular interior rearview mirror assembly includes a mounting assembly having a base portion and a mounting arm extending from the base portion. A mirror head is pivotally adjustable relative to the mounting assembly via a pivot joint having first and second pivot elements. The mirror head includes a mirror reflective element, with the first pivot element disposed at the rear side of the mirror reflective element and fixed thereat. The mounting arm includes a proximal end proximate the base portion and a distal end distal from the base portion, with the second pivot element being at the distal end of the mounting arm. The second pivot element is disposed at a damping element that is received at the distal end of the mounting arm. The damping element and the second pivot element are biased toward the distal end of the mounting arm and away from the base portion.
