The aim of this research was to investigate the variation regarding the chemical composition and biological activities of needles essential oils (EOs) of  P. halepensis . Chemical profiles demonstrated a significant (P &lt; 0.05) variability among the different EOs. The main identified compounds were caryophyllene (48.77 ± 2.26), phenyl isovalerate (22.22 ± 2.26), β-myrcene (15.55 ± 5.65) and α-pinene (14.52 ± 2.26). Further, it was shown that EO from Tabouba (Tab) displayed the highest DPPH scavenging (IC 50  = 73.03 mg/mL), anti-inflammatory (IC 50  = 23.29 µg/mL) and α-glucosidase inhibition activities (IC 50  = 254.45 µg/mL). While Elmahres (Elm) exhibited the most potent ABTS radical’s inhibition (IC 50  = 197.87 mg/mL). For the cytotoxic capacities, Kettana (Ket) was the most efficient against breast cancer MCF-7 cell line with IC 50  value better than doxorubicin used as positive control. Obtained results suggest that EO of  P. halepensis  could be used as a source of bioactive compounds.
