Generalized Cesàro operators $$C_t$$
C
t
, for $$t\in [0,1)$$
t

, are investigated when they act on the disc algebra $$A({\mathbb {D}})$$
A
(
D
)
and on the Hardy spaces $$H^p$$
H
p
, for $$1\le p \le \infty $$

. We study the continuity, compactness, spectrum and point spectrum of $$C_t$$
C
t
as well as their linear dynamics and mean ergodicity on these spaces.
