PROBLEM TO BE SOLVED: To provide a room temperature curing organopolysiloxane composition having excellent non-sagging properties and affording excellent rubber physical properties by curing at room temperature. SOLUTION: The room temperature curing organopolysiloxane composition is characterized as comprising (A) 100 pts.mass of a diorganopolysiloxane having hydroxy groups at both terminals and/or a diorganopolysiloxane having alkoxysilyl groups at both the terminals, (B) 0.1-10 pts.mass of a polyoxypropylene-modified silicone, (C) 1-50 pts.mass of wet silica and (D) 1-20 pts.mass of a silane or a siloxane having at least 3 silicon atom-bonded hydrolyzable groups in one molecule.
