Joseph Richard Grenier (4 July 1852 – 26 May 1926), a Frenchman by descent, was a barrister and a Puisne Judge of the Supreme Court of Ceylon.

In 1873, he was admitted an advocate of the Supreme Court of Ceylon, and in 1906 was called to the English Bar at Gray's Inn.

[1][2][3] Grenier began his career practising in Jaffna but subsequently went to Colombo where he held various judicial appointments under the Ceylon Government.

In 1910, he rose to the Bench of the Supreme Court as Puisne Judge but retired on reaching the age limit.

His autobiography "Leaves from my Life" published in 1923 attracted much attention in Ceylon owing to the candour with which he wrote of people and events.
