Sir Thomas Duncombe Love Jones-Parry, 1st Baronet (5 January 1832 – 18 December 1891) was a Welsh landowner who was Liberal Member of Parliament for Caernarvonshire and one of the founders of the Welsh settlement in Patagonia.
Love Jones-Parry inherited the Madryn estate near Nefyn from his father, Sir Love Jones-Parry. He was educated at Rugby School and Oxford University, and was High Sheriff of Caernarvonshire in 1854. He was a prominent figure in eisteddfodic circles, where he had the bardic name "Elphin".
Jones-Parry rose to prominence in politics when he won the Caernarvonshire seat in the 1868 election, defeating the Tory candidate, Douglas Pennant (later Lord Penrhyn). He lost this seat at the next election, but won the Caernarvon Boroughs seat at a by-election in 1882 and held it until 1886. He was made a baronet by Gladstone for his services to the Liberal Party.
Towards the end of 1862 Captain Love Jones-Parry, accompanied by Lewis Jones, left for Patagonia to decide whether it was a suitable area for Welsh emigrants. The trip was largely financed by Jones-Parry, who paid at least £750 from his own pocket. They first visited Buenos Aires where they held discussions with the Interior Minister Guillermo Rawson then, having come to an agreement, they headed south. They reached Patagonia in a small ship named the Candelaria, and were driven by a storm into a bay which they named "Porth Madryn" after Jones-Parry's estate in Wales. The town which grew near the spot where they landed is now named Puerto Madryn .
