'''Троугао''' ({{јез-лат|Triangulum}}) је једно од 88 савремених и 48 оригиналних [[Клаудије Птолемеј|Птоломејевих]] [[сазвежђе|сазвежђа]]. Првобитно је названо ''-{Deltoton}-'', по [[rečna delta|делти]] [[Нил]]а. У [[17. век]]у је [[пољаци|пољски]] [[астрономија|астроном]] [[Петар Планције]] поред Троугла сместио и Мали троугао (''-{Triangulum Minus}-''), али се то сазвежђе више не користи. Троугао је једно од најмањих сазвежђа [[северна хемисфера|северне хемисфере]].

У Троуглу се налази један [[Mesjeov katalog|Месјеов објекат]] — М33 или [[галаксија]] Троугао. М33 је трећа највећа галаксија у [[Локална група галаксија|Локалној групи]], пречника 50.000 светлосних година. Удаљена је од Сунца око 3 милиона светлосних година, а по типу је [[спирална галаксија]].
У Троуглу се налази и неколико других галаксија, али ниједна сјајнија од 11. магнитуде. Највећа је спирална галаксија са пречком -{[[NGC 925]]}-, удаљена од Сунца око 45 милиона светлосних година.
