The thick-billed seedeater (Crithagra burtoni) is a species of finch in the family Fringillidae. It is native to the Western High Plateau and Bioko, the Albertine rift montane forests and the East African montane forests

The thick-billed seedeater was formerly placed in the genus Serinus but phylogenetic analysis using mitochondrial and nuclear DNA sequences found that the genus was polyphyletic.{{cite journal | last1=Zuccon | first1=Dario | last2=Prŷs-Jones | first2=Robert | last3=Rasmussen | first3=Pamela C. | last4=Ericson | first4=Per G.P. | year=2012 | title=The phylogenetic relationships and generic limits of finches (Fringillidae) | journal=Molecular Phylogenetics and Evolution | volume=62 | issue=2 | pages=581–596 | doi=10.1016/j.ympev.2011.10.002 | url=http://www.nrm.se/download/18.9ff3752132fdaeccb6800010935/Zuccon%20et%20al%202012.pdf | pmid=22023825}} The genus was therefore split and a number of species including the thick-billed seedeater were moved to the resurrected genus Crithagra.{{cite web| editor1-last=Gill | editor1-first=Frank | editor2-last=Donsker | editor2-first=David | title=Finches, euphonias | work= World Bird List Version 5.2| url=http://www.worldbirdnames.org/bow/finches/ | publisher=International Ornithologists' Union| access-date=5 June 2015 }}{{cite journal | last=Swainson | first=William | author-link=William Swainson | year=1827 | title=On several forms in ornithology not hitherto defined | journal=Zoological Journal | volume=3 | page=348 | url=https://www.biodiversitylibrary.org/page/2339407 }}
