James Clark Baker (13 November 1866 – 1 February 1939), also known as James Clark, was an English-born New Zealand cricketer who played first-class cricket for Otago between the 1889/90 and 1906/07 seasons.

When he made 103, Otago's first-ever century, on New Year's Day 1902 at the Carisbrook ground against Hawke's Bay, the Otago Daily Times said "the burly Grange man gave an exhibition that is not likely to be eclipsed for many a day ... his strokes were powerful and clean".

[10][11] The New Zealand cricket historian Tom Reese regarded Baker as the best batsman in New Zealand in the 1890s, describing him as "a solid player in every way, at home on fast or slow wickets, and combining good defence with hitting ability".

[11] Clark Baker was born in London in 1866 and emigrated to New Zealand in about 1880, settling at Dunedin.

[12] On the day of Baker's funeral the Otago and Canterbury players paused for a minute or two during their Plunket Shield match at Carisbrook as a mark of respect.
