This study aimed to comprehensively evaluate the antioxidant and anticancer potential of methanolic twig extracts from seven Annonaceae species. &lt;strong&gt;Methods: &lt;/strong&gt;Twig specimens from &lt;em&gt;Cananga latifolia, Goniothalamus elegans, Goniothalamus tamirensis, Melodorum fructicosum, Polyalthia dubia, Polyalthia cerasoides&lt;/em&gt;, and &lt;em&gt;Uvaria fauveliana&lt;/em&gt; were subjected to standardized methanolic extraction. Antioxidant activity was assessed using DPPH radical scavenging assay. Anticancer potential was evaluated through Sulforhodamine B assay against three human cancer cell lines and normal human dermal fibroblasts at 25 μg/mL concentration. &lt;strong&gt;Results:&lt;/strong&gt; &lt;em&gt;Goniothalamus elegans&lt;/em&gt; demonstrated exceptional antioxidant activity (IC50 = 5.62 ± 1.21 μg/mL) comparable to ascorbic acid. In anticancer evaluation, &lt;em&gt;G. elegans &lt;/em&gt;exhibited remarkable cytotoxicity against MCF-7 (95.19 ± 0.62%) and HeLa (94.46 ± 1.69%) cancer cells while demonstrating exceptional selectivity with minimal toxicity toward normal cells (19.72 ± 1.19%). Melodorum fructicosum showed highest activity against HT-29 colon cancer cells (75.84 ± 1.57%). &lt;strong&gt;Conclusions:&lt;/strong&gt; &lt;em&gt;Goniothalamus elegans&lt;/em&gt; demonstrated exceptional dual bioactivity with both potent antioxidant properties and selective anticancer effects. The remarkable selectivity indices and broad-spectrum anticancer activity suggest significant clinical potential. These findings provide scientific validation for traditional medicinal uses of Annonaceae species.&lt;/p&gt;
